BACKGROUND

Activation of naive CD4+ T helper cells results in the development of at least two distinct effector populations, Th1 cells and Th2 cells. See U.S. Pat. No. 7,470,428, Mosmann T R et al. (1986) J Immunol 136:2348-57; Mosmann T R et al. (1996) Immunol Today 17:138-46; Abbas A K et al. (1996) Nature 383:787-793. Th1 cells produce cytokines (e.g., interferon gamma, interleukin-2, tumor necrosis factor alpha, and lymphotoxin) which are commonly associated with cell-mediated immune responses against intracellular pathogens, delayed-type hypersensitivity reactions (Sher A et al. (1992) Annu Rev Immunol 10:385-409), and induction of organ-specific autoimmune diseases. Liblau R S et al. (1995) Immunol Today 16:34-38. Th2 cells produce cytokines (e.g., IL-4, IL-10, and IL-13) that are crucial for control of extracellular helminthic infections and promote atopic and allergic diseases. Sher A et al. (1992) Annu Rev Immunol 10:385-409. In addition to their distinct roles in disease, the Th1 and Th2 cells cross-regulate each other's expansion and functions. Thus, preferential induction of Th2 cells inhibits autoimmune diseases (Kuchroo V K et al. (1995) Cell 80:707-18; Nicholson L B et al. (1995) Immunity 3:397-405), and predominant induction of Th1 cells can regulate induction of asthma, atopy and allergies. Lack G et al. (1994) J Immunol 152:2546-54; Hofstra C L et al. (1998) J Immunol 161:5054-60.

TIM-3 is a transmembrane receptor protein that is expressed, e.g., on Th1 (T helper 1) CD4+ cells and cytotoxic CD8+ T cells that secrete IFN-γ. TIM-3 is generally not expressed on naïve T cells but rather upregulated on activated, effector T cells. TIM-3 has a role in regulating immunity and tolerance in vivo (see Hastings et al., Eur J Immunol. 2009 September; 39(9):2492-501). There is a need in the art for new molecules that regulate TIM-3 function and the function of TIM-3 expressing cells.

DETAILED DESCRIPTION

T-cell immunoglobulin domain and mucin domain 3 (TIM-3, also known as Hepatitis A virus cellular receptor 2, and HAVCR2) is a cell surface protein expressed, e.g., on activated CD4+ and CD8+ T cells, natural regulatory T cells (nTregs), NK cells, and innate cells, e.g., macrophages, monocytes and dendritic cells (DCs). TIM-3 is generally not expressed on naïve T cells, but rather upregulated on activated, effector T cells, e.g., on a PD-1+ subset of cells. TIM-3 is also expressed on tissue site natural regulatory cells and in murine models. TIM-3+ Tregs have been shown to have a more suppressive phenotype while TIM-3+ Tregs have also been shown to correlate with disease severity in NSCLC, hepatocellular and ovarian carcinoma. TIM-3 is constitutively expressed on DCs, monocytes/macrophages and NK cells, and blockade of TIM-3 has been shown to correlate with increased cytotoxicity in NK cells; increased secretion of IL-12/TNF-α by monocytes/macrophages; and increased NF-κB expression in DCs. Blockade of TIM-3 (partially alone and additively or synergistically in combination with PD-1 pathway blockade) has shown anti-tumor efficacy in several preclinical cancer models, including CT26 colon carcinoma (Sakuishi et al., J Exp Med. 2010; 207(10):2187-94), WT3 sarcoma and TRAMP-C1 prostate carcinoma (Ngiow et al., Cancer Res. 2011; 71(10):3540-3551). Recent studies have highlighted TIM-3 as an important player in the T effector cell exhaustion and suppression that takes place in chronic immune conditions such as infection, e.g., bacterial or viral, and cancer in both humans and experimental models. TIM-3 has been described as an inhibitory receptor in the immunological synapse, and blocking of TIM-3 may enhance immune response against infection and cancer.

Blockade of TIM-3 has been shown to restore activity in effector cells, such as cytokine secretion and proliferation. In virally exhausted cell populations, e.g., cells infected with HCV, TIM-3-expressing cells (TIM3+ cells) express less TNF-alpha and IFN-gamma cytokines than TIM-3 negative cells in both effector cell populations, CD4+ and CD8+ T cells (Golden-Mason et al., 2009, J. Virol, 83:9122). Blockade of TIM-3 restores proliferation in CD8+ T cells from an HIV patient, or in cells that recapitulate viral exhaustion (Jones et al., 2008, J. Exp. Med., 205:2763), or proliferation and IFN-γ and/or TNF-α secretion in NY-ESO-1 specific T cells from PBMCs from metastatic patients (Fourcade et al., 2010, J. Exp. Med., 207:2175). TIM-3 blockade may also diminish the suppressor activity of regulatory T cells. TIM-3+ T cells have been found to be concentrated in tumors, and contribute to the immunosuppressive tumor environment (Sakuishi et al., 2013, Oncoimmunology, 2:e23849; Gao et al., 2012, Plos One; and Yan et al., 2013, Plos One.). Thus, blockade of TIM-3, e.g., by antibodies that inhibit TIM-3 function, can improve the immune response against infection and anti-tumor immunity.

TIM-3 has also been implicated in regulating immune response through macrophage activity. Blockade of TIM-3 leads to an increase in TLR-mediated IL-12 production (Zhang et al., 2010, J Leukoc Biol, 91:189). Thus, TIM-3 blockade may increase immune stimulation properties of macrophages to enhance immune response against infection and anti-tumor activity.

TIM-3 has five reported ligands: Galectin-9 (Gal-9), phosphatidylserine (PtdSer), HMGB1, Semaphorin-4A, and CEACAM-1. S-type lectin galectin-9 can inhibit TIM-3-associated Th1 effector function and induce apoptosis on TIM-3-expressing T cells in murine models. PtdSer usually resides on the intracellular side of the plasma membrane, but is flipped to the extracellular side during apoptosis. PtdSer binds a preserved cleft in all three human TIM family members (TIM-1, 3, 4). Inhibition of PtdSer binding to TIM-3 may activate T-cell response. Galectin-9 is secreted by tumor cells and can contribute to evasion from anti-tumor immunity. DNA alarmin HMGB1, for which TIM-3 may act as a “sink,” can prevent the HMGB1/RAGE interactions that stimulate innate immunity. Semaphorin-4A and CEACAM-1 (another immune checkpoint molecule whose inhibition can enhance immune response) can interact with TIM-3 both in cis as a heterodimer on T cells and in trans as a ligand. Interaction between CEACAM-1 and TIM-3 may help mediate block immune response signaling. Co-blockade of TIM-3 and CEACAM-1 in CT26 colon carcinoma showed similar efficacy to that seen for co-blockade of PD-L1 and TIM-3.

The TIM-3 cytoplasmic tail has seven sites for tyrosine phosphorylation and no known inhibitory (i.e., ITIM) motifs, which suggests that TIM-3 could co-stimulate with the T cell receptor, leading to functional exhaustion through increased T cell signaling. TIM-3 can interact with Fyn and facilitate accumulation of receptor phosphatases CD148 and CD45 at the immunologic synapse. The presence of CEACAM-1 as a co-receptor in the TIM-3/CEACAM-1 heterodimer suggests that this co-expression may lead to inhibitory signaling in T cells via the ITIM motif in the CEACAM-1 cytoplasmic tail which has been shown to interact with both SHP1 and SHP2.

Disclosed herein are antibody molecules that bind to TIM-3 with high affinity and specificity. In one embodiment, humanized antibodies against TIM-3 are disclosed. Additional aspects of the invention include nucleic acid molecules encoding the antibody molecules, expression vectors, host cells and methods for making the antibody molecules are also provided. Immunoconjugates, multi- or bispecific antibody molecules and pharmaceutical compositions comprising the antibody molecules are also provided. The anti-TIM-3 antibody molecules disclosed herein can be used (alone or in combination with other agents or therapeutic modalities) to treat, prevent and/or diagnose immune disorders, cancer, infectious disease, Crohn's disease, sepsis, SIRS (Systemic Inflammatory Response Syndrome), and glomerulonephritis. Thus, compositions and methods for detecting TIM-3, as well as methods for treating various disorders, including cancer and immune disorders using the anti-TIM-3 antibody molecules are disclosed herein.

The term “TIM-3” include isoforms, mammalian, e.g., human TIM-3, species homologs of human TIM-3, and analogs comprising at least one common epitope with TIM-3. The amino acid sequence of TIM-3, e.g, human TIM-3, is known in the art, e.g., Sabatos et al., 2003. Nat Immunol, 4(11):1102.

Definitions

As used herein, the articles “a” and “an” refer to one or to more than one (e.g., to at least one) of the grammatical object of the article.

The term “or” is used herein to mean, and is used interchangeably with, the term “and/or”, unless context clearly indicates otherwise.

“About” and “approximately” shall generally mean an acceptable degree of error for the quantity measured given the nature or precision of the measurements. Exemplary degrees of error are within 20 percent (%), typically, within 10%, and more typically, within 5% of a given value or range of values.

The compositions and methods disclosed herein encompass polypeptides and nucleic acids having the sequences specified, or sequences substantially identical or similar thereto, e.g., sequences at least 85%, 90%, 95% identical or higher to the sequence specified. In the context of an amino acid sequence, the term “substantially identical” is used herein to refer to a first amino acid that contains a sufficient or minimum number of amino acid residues that are i) identical to, or ii) conservative substitutions of aligned amino acid residues in a second amino acid sequence such that the first and second amino acid sequences can have a common structural domain and/or common functional activity. For example, amino acid sequences that contain a common structural domain having at least about 85%, 90%. 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99% identity to a reference sequence, e.g., a sequence provided herein.

In the context of nucleotide sequence, the term “substantially identical” is used herein to refer to a first nucleic acid sequence that contains a sufficient or minimum number of nucleotides that are identical to aligned nucleotides in a second nucleic acid sequence such that the first and second nucleotide sequences encode a polypeptide having common functional activity, or encode a common structural polypeptide domain or a common functional polypeptide activity. For example, nucleotide sequences having at least about 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99% identity to a reference sequence, e.g., a sequence provided herein.

The term “functional variant” refers polypeptides that have a substantially identical amino acid sequence to the naturally-occurring sequence, or are encoded by a substantially identical nucleotide sequence, and are capable of having one or more activities of the naturally-occurring sequence.

To determine the percent identity of two amino acid sequences, or of two nucleic acid sequences, the sequences are aligned for optimal comparison purposes (e.g., gaps can be introduced in one or both of a first and a second amino acid or nucleic acid sequence for optimal alignment and non-homologous sequences can be disregarded for comparison purposes). In a preferred embodiment, the length of a reference sequence aligned for comparison purposes is at least 30%, e.g., at least 40%, 50%, 60%, e.g., at least 70%, 80%, 90%, 100% of the length of the reference sequence. The amino acid residues or nucleotides at corresponding amino acid positions or nucleotide positions are then compared. When a position in the first sequence is occupied by the same amino acid residue or nucleotide as the corresponding position in the second sequence, then the molecules are identical at that position.

The percent identity between the two sequences is a function of the number of identical positions shared by the sequences, taking into account the number of gaps, and the length of each gap, which need to be introduced for optimal alignment of the two sequences.

The comparison of sequences and determination of percent identity between two sequences can be accomplished using a mathematical algorithm. In a some embodiments, the percent identity between two amino acid sequences is determined using the Needleman and Wunsch ((1970) J. Mol. Biol. 48:444-453) algorithm which has been incorporated into the GAP program in the GCG software package (available at http://www.gcg.com), using either a Blossum 62 matrix or a PAM250 matrix, and a gap weight of 16, 14, 12, 10, 8, 6, or 4 and a length weight of 1, 2, 3, 4, 5, or 6. In certain embodiments, the percent identity between two nucleotide sequences is determined using the GAP program in the GCG software package (available at http://www.gcg.com), using a NWSgapdna.CMP matrix and a gap weight of 40, 50, 60, 70, or 80 and a length weight of 1, 2, 3, 4, 5, or 6. One suitable set of parameters (and the one that should be used unless otherwise specified) are a Blossum 62 scoring matrix with a gap penalty of 12, a gap extend penalty of 4, and a frameshift gap penalty of 5.

The percent identity between two amino acid or nucleotide sequences can be determined using the algorithm of E. Meyers and W. Miller ((1989) CABIOS, 4:11-17) which has been incorporated into the ALIGN program (version 2.0), using a PAM120 weight residue table, a gap length penalty of 12 and a gap penalty of 4.

The nucleic acid and protein sequences described herein can be used as a “query sequence” to perform a search against public databases to, for example, identify other family members or related sequences. Such searches can be performed using the NBLAST and XBLAST programs (version 2.0) of Altschul, et al. (1990) J. Mol. Biol. 215:403-10. BLAST nucleotide searches can be performed with the NBLAST program, score=100, wordlength=12 to obtain nucleotide sequences homologous to a nucleic acid as described herein. BLAST protein searches can be performed with the XBLAST program, score=50, wordlength=3 to obtain amino acid sequences homologous to protein molecules described herein. To obtain gapped alignments for comparison purposes, Gapped BLAST can be utilized as described in Altschul et al., (1997) Nucleic Acids Res. 25:3389-3402. When utilizing BLAST and Gapped BLAST programs, the default parameters of the respective programs (e.g., XBLAST and NBLAST) can be used. See www.ncbi.nlm.nih.gov.

As used herein, the term “hybridizes under low stringency, medium stringency, high stringency, or very high stringency conditions” describes conditions for hybridization and washing. Guidance for performing hybridization reactions can be found in Current Protocols in Molecular Biology, John Wiley & Sons, N.Y. (1989), 6.3.1-6.3.6, which is incorporated by reference. Aqueous and nonaqueous methods are described in that reference and either can be used. Specific hybridization conditions referred to herein are as follows: 1) low stringency hybridization conditions in 6× sodium chloride/sodium citrate (SSC) at about 45° C., followed by two washes in 0.2×SSC, 0.1% SDS at least at 50° C. (the temperature of the washes can be increased to 55° C. for low stringency conditions); 2) medium stringency hybridization conditions in 6×SSC at about 45° C., followed by one or more washes in 0.2×SSC, 0.1% SDS at 60° C.; 3) high stringency hybridization conditions in 6×SSC at about 45° C., followed by one or more washes in 0.2×SSC, 0.1% SDS at 65° C.; and preferably 4) very high stringency hybridization conditions are 0.5M sodium phosphate, 7% SDS at 65° C., followed by one or more washes at 0.2×SSC, 1% SDS at 65° C. Very high stringency conditions (4) are suitable conditions and the ones that should be used unless otherwise specified.

It is understood that the molecules described herein may have additional conservative or non-essential amino acid substitutions, which do not have a substantial effect on their functions.

A “conservative amino acid substitution” is one in which the amino acid residue is replaced with an amino acid residue having a similar side chain. Families of amino acid residues having similar side chains have been defined in the art. These families include amino acids with basic side chains (e.g., lysine, arginine, histidine), acidic side chains (e.g., aspartic acid, glutamic acid), uncharged polar side chains (e.g., glycine, asparagine, glutamine, serine, threonine, tyrosine, cysteine), nonpolar side chains (e.g., alanine, valine, leucine, isoleucine, proline, phenylalanine, methionine, tryptophan), beta-branched side chains (e.g., threonine, valine, isoleucine) and aromatic side chains (e.g., tyrosine, phenylalanine, tryptophan, histidine).

The terms “polypeptide”, “peptide” and “protein” (if single chain) are used interchangeably herein.

The terms “nucleic acid,” “nucleic acid sequence,” “nucleotide sequence,” or “polynucleotide sequence,” and “polynucleotide” are used interchangeably.

The term “isolated,” as used herein, refers to material that is removed from its original or native environment (e.g., the natural environment if it is naturally occurring). For example, a naturally-occurring polynucleotide or polypeptide present in a living animal is not isolated, but the same polynucleotide or polypeptide, separated by human intervention from some or all of the co-existing materials in the natural system, is isolated. Such polynucleotides could be part of a vector and/or such polynucleotides or polypeptides could be part of a composition, and still be isolated in that such vector or composition is not part of the environment in which it is found in nature.

Various aspects of the compositions and methods herein are described in further detail below. Additional definitions are set out throughout the specification.

In another example, an antibody molecule includes two heavy (H) chain variable domain sequences and two light (L) chain variable domain sequence, thereby forming two antigen binding sites, such as Fab, Fab′, F(ab′)₂, Fc, Fd, Fd′, Fv, single chain antibodies (scFv for example), single variable domain antibodies, diabodies (Dab) (bivalent and bispecific), and chimeric (e.g., humanized) antibodies, which may be produced by the modification of whole antibodies or those synthesized de novo using recombinant DNA technologies. These functional antibody fragments retain the ability to selectively bind with their respective antigen or receptor. Antibodies and antibody fragments can be from any class of antibodies including, but not limited to, IgG, IgA, IgM, IgD, and IgE, and from any subclass (e.g., IgG1, IgG2, IgG3, and IgG4) of antibodies. The preparation of antibody molecules can be monoclonal or polyclonal. An antibody molecule can also be a human, humanized, CDR-grafted, or in vitro generated antibody. The antibody can have a heavy chain constant region chosen from, e.g., IgG1, IgG2, IgG3, or IgG4. The antibody can also have a light chain chosen from, e.g., kappa or lambda. The term “immunoglobulin” (Ig) is used interchangeably with the term “antibody” herein.

Examples of antigen-binding fragments of an antibody molecule include: (i) a Fab fragment, a monovalent fragment consisting of the VL, VH, CL and CH1 domains; (ii) a F(ab′)2 fragment, a bivalent fragment comprising two Fab fragments linked by a disulfide bridge at the hinge region; (iii) a Fd fragment consisting of the VH and CH1 domains; (iv) a Fv fragment consisting of the VL and VH domains of a single arm of an antibody, (v) a diabody (dAb) fragment, which consists of a VH domain; (vi) a camelid or camelized variable domain; (vii) a single chain Fv (scFv), see e.g., Bird et al. (1988) Science 242:423-426; and Huston et al. (1988) Proc. Natl. Acad. Sci. USA 85:5879-5883); (viii) a single domain antibody. These antibody fragments may be obtained using any suitable method, including several conventional techniques known to those with skill in the art, and the fragments can be screened for utility in the same manner as are intact antibodies.

The term “antibody” includes intact molecules as well as functional fragments thereof. Constant regions of the antibodies can be altered, e.g., mutated, to modify the properties of the antibody (e.g., to increase or decrease one or more of: Fc receptor binding, antibody glycosylation, the number of cysteine residues, effector cell function, or complement function).

The antibodies disclosed herein can also be single domain antibodies. Single domain antibodies can include antibodies whose complementary determining regions are part of a single domain polypeptide. Examples include, but are not limited to, heavy chain antibodies, antibodies naturally devoid of light chains, single domain antibodies derived from conventional 4-chain antibodies, engineered antibodies and single domain scaffolds other than those derived from antibodies. Single domain antibodies may be any of the art, or any future single domain antibodies. Single domain antibodies may be derived from any species including, but not limited to mouse, human, camel, llama, fish, shark, goat, rabbit, and bovine. According to some aspects, a single domain antibody is a naturally occurring single domain antibody known as heavy chain antibody devoid of light chains. Such single domain antibodies are disclosed in WO 9404678, for example. For clarity reasons, this variable domain derived from a heavy chain antibody naturally devoid of light chain is known herein as a VHH or nanobody to distinguish it from the conventional VH of four chain immunoglobulins. Such a VHH molecule can be derived from antibodies raised in Camelidae species, for example in camel, llama, dromedary, alpaca and guanaco. Other species besides Camelidae may produce heavy chain antibodies naturally devoid of light chain; such VHHs are also contemplated.

The VH and VL regions can be subdivided into regions of hypervariability, termed “complementarity determining regions” (CDR), interspersed with regions that are more conserved, termed “framework regions” (FR). The extent of the framework region and CDRs has been precisely defined by a number of methods (see, Kabat, E. A., et al. (1991) Sequences of Proteins of Immunological Interest, Fifth Edition, U.S. Department of Health and Human Services, NIH Publication No. 91-3242; Chothia, C. et al. (1987) J. Mol. Biol. 196:901-917; and the AbM definition used by Oxford Molecular's AbM antibody modeling software. See, generally, e.g., Protein Sequence and Structure Analysis of Antibody Variable Domains. In: Antibody Engineering Lab Manual (Ed.: Duebel, S. and Kontermann, R., Springer-Verlag, Heidelberg). In some embodiments, the following definitions are used: AbM definition of CDR1 of the heavy chain variable domain and Kabat definitions for the other CDRs. In certain embodiments, Kabat definitions are used for all CDRs. In addition, embodiments described with respect to Kabat or AbM CDRs may also be implemented using Chothia hypervariable loops. Each VH and VL typically includes three CDRs and four FRs, arranged from amino-terminus to carboxy-terminus in the following order: FR1, CDR1, FR2, CDR2, FR3, CDR3, FR4.

As used herein, an “immunoglobulin variable domain sequence” refers to an amino acid sequence which can form the structure of an immunoglobulin variable domain. For example, the sequence may include all or part of the amino acid sequence of a naturally-occurring variable domain. For example, the sequence may or may not include one, two, or more N- or C-terminal amino acids, or may include other alterations that are compatible with formation of the protein structure.

The term “antigen-binding site” refers to the part of an antibody molecule that comprises determinants that form an interface that binds to a TIM-3 polypeptide, or an epitope thereof. With respect to proteins (or protein mimetics), the antigen-binding site typically includes one or more loops (of at least, e.g., four amino acids or amino acid mimics) that form an interface that binds to the TIM-3 polypeptide. Typically, the antigen-binding site of an antibody molecule includes at least one or two CDRs, or more typically at least three, four, five or six CDRs.

The terms “compete” or “cross-compete” are used interchangeably herein to refer to the ability of an antibody molecule to interfere with binding of an anti-TIM-3 antibody molecule, e.g., an anti-TIM-3 antibody molecule provided herein, to a target, e.g., human TIM-3. The interference with binding can be direct or indirect (e.g., through an allosteric modulation of the antibody molecule or the target). The extent to which an antibody molecule is able to interfere with the binding of another antibody molecule to the target, and therefore whether it can be said to compete, can be determined using a competition binding assay, for example, a FACS assay, an ELISA or BIACORE assay. In some embodiments, a competition binding assay is a quantitative competition assay. In some embodiments, a first anti-TIM-3 antibody molecule is said to compete for binding to the target with a second anti-TIM-3 antibody molecule when the binding of the first antibody molecule to the target is reduced by 10% or more, e.g., 20% or more, 30% or more, 40% or more, 50% or more, 55% or more, 60% or more, 65% or more, 70% or more, 75% or more, 80% or more, 85% or more, 90% or more, 95% or more, 98% or more, 99% or more in a competition binding assay (e.g., a competition assay described herein).

As used herein, the term “epitope” refers to the moieties of an antigen (e.g., human TIM-3) that specifically interact with an antibody molecule. Such moieties, referred to herein as epitopic determinants, typically comprise, or are part of, elements such as amino acid side chains or sugar side chains. An epitopic determinant can be defined by methods known in the art or disclosed herein, e.g., by crystallography or by hydrogen-deuterium exchange. At least one or some of the moieties on the antibody molecule, that specifically interact with an epitopic determinant, are typically located in a CDR(s). Typically an epitope has a specific three dimensional structural characteristics. Typically an epitope has specific charge characteristics. Some epitopes are linear epitopes while others are conformational epitopes.

In an embodiment, an epitopic determinant is a moiety on the antigen, e.g., such as amino acid side chain or sugar side chain, or part thereof, which, when the antigen and antibody molecule are co-crystallized, is within a predetermined distance, e.g., within 5 Angstroms, of a moiety on the antibody molecule, referred to herein as a “crystallographic epitopic determinant.” The crystallographic epitopic determinants of an epitope are collectively refered to as the “crystallographic epitope.”

A first antibody molecule binds the same epitope as a second antibody molecule (e.g., a reference antibody molecule, e.g., an antibody molecule disclosed herein, e.g., ABTIM3-hum21, ABTIM-hum11 or ABTIM3-hum03) if the first antibody specifically interacts with the same epitopic determinants on the antigen as does the second or reference antibody, e.g., when interaction is measured in the same way for both the antibody and the second or reference antibody. Epitopes that overlap share at least one epitopic determinant. A first antibody molecule binds an overlapping epitope with a second antibody molecule (e.g., a reference antibody molecule, e.g., an antibody disclosed herein, e.g., ABTIM3-hum21, ABTIM-hum11 or ABTIM3-hum03) when both antibody molecules specifically interact with a common epitopic determinant. A first and a second antibody molecule (e.g., a reference antibody molecule, e.g., an antibody molecule disclosed herein, e.g., ABTIM3-hum21, ABTIM-hum11 or ABTIM3-hum03) bind substantially overlapping epitopes if at least half of the epitopic determinants of the second or reference antibody are found as epitopic determinants in the epitope of the first antibody. A first and a second antibody molecule (e.g., a reference antibody molecule, e.g., an antibody molecule disclosed herein, e.g., ABTIM3-hum21, ABTIM-hum11 or ABTIM3-hum03) bind substantially the same epitope if the first antibody molecule binds at least half of the core epitopic determinants of the epitope of the second or reference antibody, wherein the core epitopic determinants are defined by crystallography and hydrogen-deuterium exchange, e.g., including residues Val24, Glu25, Thr41, Glu121, Lys122, Phe123, Asn124, Leu125, Lys126, Leu127, Val128, Gly56, Ala57, Cys58, Pro59, Val60, and Phe61 of human TIM-3.

The terms “monoclonal antibody” or “monoclonal antibody composition” as used herein refer to a preparation of antibody molecules of single molecular composition. A monoclonal antibody composition displays a single binding specificity and affinity for a particular epitope. A monoclonal antibody can be made by hybridoma technology or by methods that do not use hybridoma technology (e.g., recombinant methods).

An “effectively human” protein is a protein that does not evoke a neutralizing antibody response, e.g., the human anti-murine antibody (HAMA) response. HAMA can be problematic in a number of circumstances, e.g., if the antibody molecule is administered repeatedly, e.g., in treatment of a chronic or recurrent disease condition. A HAMA response can make repeated antibody administration potentially ineffective because of an increased antibody clearance from the serum (see, e.g., Saleh et al., Cancer Immunol. Immunother., 32:180-190 (1990)) and also because of potential allergic reactions (see, e.g., LoBuglio et al., Hybridoma, 5:5117-5123 (1986)).

The antibody molecule can be a polyclonal or a monoclonal antibody. In other embodiments, the antibody can be recombinantly produced, e.g., produced by any suitable phage display or combinatorial methods.

Various phage display and combinatorial methods for generating antibodies are known in the art (as described in, e.g., Ladner et al. U.S. Pat. No. 5,223,409; Kang et al. International Publication No. WO 92/18619; Dower et al. International Publication No. WO 91/17271; Winter et al. International Publication WO 92/20791; Markland et al.

(1991) Nature 352:624-628; Gram et al. (1992) PNAS 89:3576-3580; Garrad et al. (1991) Bio/Technology 9:1373-1377; Hoogenboom et al. (1991) Nuc Acid Res 19:4133-4137; and Barbas et al. (1991) PNAS 88:7978-7982, the contents of all of which are incorporated by reference herein).

In some embodiments, the antibody is a fully human antibody (e.g., an antibody made in a mouse which has been genetically engineered to produce an antibody from a human immunoglobulin sequence), or a non-human antibody, e.g., a rodent (mouse or rat), goat, primate (e.g., monkey), camel antibody. In certain embodiments, the non-human antibody is a rodent (mouse or rat antibody). Methods of producing rodent antibodies are known in the art.

Human monoclonal antibodies can be generated using transgenic mice carrying the human immunoglobulin genes rather than the mouse system. Splenocytes from these transgenic mice immunized with the antigen of interest are used to produce hybridomas that secrete human mAbs with specific affinities for epitopes from a human protein (see, e.g., Wood et al.

International Application WO 91/00906, Kucherlapati et al. PCT publication WO 91/10741; Lonberg et al. International Application WO 92/03918; Kay et al. International Application 92/03917; Lonberg, N. et al. 1994 Nature 368:856-859; Green, L. L. et al. 1994 Nature Genet. 7:13-21; Morrison, S. L. et al. 1994 Proc. Natl. Acad. Sci. USA 81:6851-6855; Bruggeman et al. 1993 Year Immunol 7:33-40; Tuaillon et al. 1993 PNAS 90:3720-3724; Bruggeman et al. 1991 Eur J Immunol 21:1323-1326).

An antibody can be one in which the variable region, or a portion thereof, e.g., the CDRs, are generated in a non-human organism, e.g., a rat or mouse. Chimeric, CDR-grafted, and humanized antibodies are also contemplated. Antibodies generated in a non-human organism, e.g., a rat or mouse, and then modified, e.g., in the variable framework or constant region, to decrease antigenicity in a human are also contemplated.

Chimeric antibodies can be produced by any suitable recombinant DNA technique. Several are known in the art (see Robinson et al., International Patent Publication PCT/US86/02269; Akira, et al., European Patent Application 184,187; Taniguchi, M., European Patent Application 171,496; Morrison et al., European Patent Application 173,494; Neuberger et al., International Application WO 86/01533; Cabilly et al. U.S. Pat. No. 4,816,567; Cabilly et al., European Patent Application 125,023; Better et al. (1988 Science 240:1041-1043); Liu et al. (1987) PNAS 84:3439-3443; Liu et al., 1987, J. Immunol. 139:3521-3526; Sun et al. (1987) PNAS 84:214-218; Nishimura et al., 1987, Canc. Res. 47:999-1005; Wood et al. (1985) Nature 314:446-449; and Shaw et al., 1988, J. Natl Cancer Inst. 80:1553-1559).

A humanized or CDR-grafted antibody will have at least one or two but generally all three recipient CDRs (of heavy and or light immunoglobulin chains) replaced with a donor CDR. The antibody may be replaced with at least a portion of a non-human CDR or only some of the CDRs may be replaced with non-human CDRs. It is only necessary to replace the number of CDRs required for binding of the humanized antibody to TIM-3. In some embodiments, the donor will be a rodent antibody, e.g., a rat or mouse antibody, and the recipient will be a human framework or a human consensus framework. Typically, the immunoglobulin providing the CDRs is called the “donor” and the immunoglobulin providing the framework is called the “acceptor.” In some embodiments, the donor immunoglobulin is a non-human (e.g., rodent). The acceptor framework is typically a naturally-occurring (e.g., a human) framework or a consensus framework, or a sequence about 85% or higher, e.g., 90%, 95%, 99% or higher identical thereto.

As used herein, the term “consensus sequence” refers to the sequence formed from the most frequently occurring amino acids (or nucleotides) in a family of related sequences (See e.g., Winnaker, From Genes to Clones (Verlagsgesellschaft, Weinheim, Germany 1987). In a family of proteins, each position in the consensus sequence is occupied by the amino acid occurring most frequently at that position in the family. If two amino acids occur equally frequently, either can be included in the consensus sequence. A “consensus framework” refers to the framework region in the consensus immunoglobulin sequence.

An antibody can be humanized by any suitable method, and several such methods known in the art (see e.g., Morrison, S. L., 1985, Science 229:1202-1207, by Oi et al., 1986, BioTechniques 4:214, and by Queen et al. U.S. Pat. Nos. 5,585,089, 5,693,761 and 5,693,762, the contents of all of which are hereby incorporated by reference).

Humanized or CDR-grafted antibodies can be produced by CDR-grafting or CDR substitution, wherein one, two, or all CDRs of an immunoglobulin chain can be replaced. See e.g., U.S. Pat. No. 5,225,539; Jones et al. 1986 Nature 321:552-525; Verhoeyan et al. 1988 Science 239:1534; Beidler et al. 1988 J. Immunol. 141:4053-4060; Winter U.S. Pat. No. 5,225,539, the contents of all of which are hereby expressly incorporated by reference. Winter describes a CDR-grafting method which may be used to prepare humanized antibodies (UK Patent Application GB 2188638A, filed on Mar. 26, 1987; Winter U.S. Pat. No. 5,225,539), the contents of which is expressly incorporated by reference.

Also provided are humanized antibodies in which specific amino acids have been substituted, deleted or added. Criteria for selecting amino acids from the donor are described in, e.g., U.S. Pat. No. 5,585,089, e.g., columns 12-16 of U.S. Pat. No. 5,585,089, the contents of which are hereby incorporated by reference. Other techniques for humanizing antibodies are described in Padlan et al. EP 519596 A1, published on Dec. 23, 1992.

The antibody molecule can be a single chain antibody. A single-chain antibody (scFV) may be engineered (see, for example, Colcher, D. et al. (1999) Ann N Y Acad Sci 880:263-80; and Reiter, Y. (1996) Clin Cancer Res 2:245-52). The single chain antibody can be dimerized or multimerized to generate multivalent antibodies having specificities for different epitopes of the same target protein.

In some embodiments, the antibody molecule has a heavy chain constant region chosen from, e.g., the heavy chain constant regions of IgG1, IgG2, IgG3, IgG4, IgM, IgA1, IgA2, IgD, and IgE; particularly, chosen from, e.g., the (e.g., human) heavy chain constant regions of IgG1, IgG2, IgG3, and IgG4. In another embodiment, the antibody molecule has a light chain constant region chosen from, e.g., the (e.g., human) light chain constant regions of kappa or lambda. The constant region can be altered, e.g., mutated, to modify the properties of the antibody (e.g., to increase or decrease one or more of: Fc receptor binding, antibody glycosylation, the number of cysteine residues, effector cell function, and/or complement function). In some embodiments the antibody has effector function and can fix complement. In other embodiments the antibody does not recruit effector cells or fix complement. In certain embodiments, the antibody has reduced or no ability to bind an Fc receptor. For example, it may be an isotype or subtype, fragment or other mutant, which does not support binding to an Fc receptor, e.g., it has a mutagenized or deleted Fc receptor binding region.

The antibody constant region is altered in some embodiments. Methods for altering an antibody constant region are known in the art. Antibodies with altered function, e.g. altered affinity for an effector ligand, such as FcR on a cell, or the C1 component of complement can be produced by replacing at least one amino acid residue in the constant portion of the antibody with a different residue (see e.g., EP 388,151 A1, U.S. Pat. Nos. 5,624,821 and 5,648,260, the contents of all of which are hereby incorporated by reference). Amino acid mutations which stabilize antibody structure, such as S228P (EU nomenclature, S241P in Kabat nomenclature) in human IgG4 are also contemplated. Similar type of alterations could be described which if applied to the murine, or other species immunoglobulin would reduce or eliminate these functions.

In some embodiments, the only amino acids in the anti-TIM-3 antibody molecule are canonical amino acids. In some embodiments, the anti-TIM-3 antibody molecule comprises naturally-occurring amino acids; analogs, derivatives and congeners thereof; amino acid analogs having variant side chains; and/or all stereoisomers of any of any of the foregoing. The anti-TIM-3 antibody molecule may comprise the D- or L-optical isomers of amino acids and peptidomimetics.

A polypeptide of an anti-TIM-3 antibody molecule may be linear or branched, it may comprise modified amino acids, and it may be interrupted by non-amino acids. The antibody molecule may also be modified; for example, by disulfide bond formation, glycosylation, lipidation, acetylation, phosphorylation, or any other manipulation, such as conjugation with a labeling component. The polypeptide can be isolated from natural sources, can be a produced by recombinant techniques from a eukaryotic or prokaryotic host, or can be a product of synthetic procedures.

An antibody molecule can be derivatized or linked to another functional molecule (e.g., another peptide or protein). As used herein, a “derivatized” antibody molecule is one that has been modified. Methods of derivatization include but are not limited to the addition of a fluorescent moiety, a radionucleotide, a toxin, an enzyme or an affinity ligand such as biotin. Accordingly, the antibody molecules are intended to include derivatized and otherwise modified forms of the antibodies described herein, including immunoadhesion molecules. For example, an antibody molecule can be functionally linked (by chemical coupling, genetic fusion, noncovalent association or otherwise) to one or more other molecular entities, such as another antibody (e.g., a bispecific antibody or a diabody), a detectable agent, a cytotoxic agent, a pharmaceutical agent, and/or a protein or peptide that can mediate association of the antibody or antibody portion with another molecule (such as a streptavidin core region or a polyhistidine tag).

Some types of derivatized antibody molecule are produced by crosslinking two or more antibodies (of the same type or of different types, e.g., to create bispecific antibodies). Suitable crosslinkers include those that are heterobifunctional, having two distinctly reactive groups separated by an appropriate spacer (e.g., m-maleimidobenzoyl-N-hydroxysuccinimide ester) or homobifunctional (e.g., disuccinimidyl suberate). Such linkers are available from Pierce Chemical Company, Rockford, Ill.

Useful detectable agents with which an anti-TIM-3 antibody molecule may be derivatized (or labeled) to include fluorescent compounds, various enzymes, prosthetic groups, luminescent materials, bioluminescent materials, fluorescent emitting metal atoms, e.g., europium (Eu), and other anthanides, and radioactive materials (described below). Exemplary fluorescent detectable agents include fluorescein, fluorescein isothiocyanate, rhodamine, 5dimethylamine-1-napthalenesulfonyl chloride, phycoerythrin and the like. An antibody may also be derivatized with detectable enzymes, such as alkaline phosphatase, horseradish peroxidase, P3-galactosidase, acetylcholinesterase, glucose oxidase and the like. When an antibody is derivatized with a detectable enzyme, it is detected by adding additional reagents that the enzyme uses to produce a detectable reaction product. For example, when the detectable agent horseradish peroxidase is present, the addition of hydrogen peroxide and diaminobenzidine leads to a colored reaction product, which is detectable. An antibody molecule may also be derivatized with a prosthetic group (e.g., streptavidin/biotin and avidin/biotin). For example, an antibody may be derivatized with biotin, and detected through indirect measurement of avidin or streptavidin binding. Examples of suitable fluorescent materials include umbelliferone, fluorescein, fluorescein isothiocyanate, rhodamine, dichlorotriazinylamine fluorescein, dansyl chloride or phycoerythrin; an example of a luminescent material includes luminol; and examples of bioluminescent materials include luciferase, luciferin, and aequorin.

Labeled antibody molecule can be used, for example, diagnostically and/or experimentally in a number of contexts, including (i) to isolate a predetermined antigen by standard techniques, such as affinity chromatography or immunoprecipitation; (ii) to detect a predetermined antigen (e.g., in a cellular lysate or cell supernatant) in order to evaluate the abundance and pattern of expression of the protein; (iii) to monitor protein levels in tissue as part of a clinical testing procedure, e.g., to determine the efficacy of a given treatment regimen.

An antibody molecule may be conjugated to another molecular entity, typically a label or a therapeutic (e.g., immunomodulatory, immunostimularoty, cytotoxic, or cytostatic) agent or moiety. Radioactive isotopes can be used in diagnostic or therapeutic applications. Radioactive isotopes that can be coupled to the anti-TIM-3 antibodies include, but are not limited to α-, β-, or γ-emitters, or β- and γ-emitters. Such radioactive isotopes include, but are not limited to iodine (¹³¹I or ¹²⁵I), yttrium (⁹⁰Y), lutetium (¹⁷⁷Lu), actinium (²²⁵Ac), praseodymium, astatine (²¹¹At), rhenium (¹⁸⁶Re), bismuth (²¹²Bi or ²¹³Bi), indium (¹¹¹In), technetium (⁹⁹mTc), phosphorus (³²P), rhodium (¹⁸⁸Rh), sulfur (³⁵S), carbon (¹⁴C), tritium (³H), chromium (⁵¹Cr), chlorine (³⁶Cl), cobalt (⁵⁷Co or ⁵⁸Co), iron (⁵⁹Fe), selenium (⁷⁵Se), or gallium (⁶⁷Ga). Radioisotopes useful as therapeutic agents include yttrium (⁹⁰Y), lutetium (¹⁷⁷Lu), actinium (²²⁵Ac), praseodymium, astatine (²¹¹At), rhenium (¹⁸⁶Re), bismuth (²¹²Bi or ²¹³Bi), and rhodium (¹⁸⁸Rh). Radioisotopes useful as labels, e.g., for use in diagnostics, include iodine (¹³¹I or ¹²⁵I), indium (¹¹¹In), technetium (⁹⁹mTc), phosphorus (³²P), carbon (¹⁴C), and tritium (³H), or one or more of the therapeutic isotopes listed above.

The present disclosure provides radiolabeled antibody molecules and methods of labeling the same. In some embodiments, a method of labeling an antibody molecule is disclosed. The method includes contacting an antibody molecule, with a chelating agent, to thereby produce a conjugated antibody. The conjugated antibody is radiolabeled with a radioisotope, e.g., ¹¹¹Indium, ⁹⁰Yttrium and ¹⁷⁷Lutetium, to thereby produce a labeled antibody molecule.

As is discussed above, the antibody molecule can be conjugated to a therapeutic agent. Therapeutically active radioisotopes have already been mentioned. Examples of other therapeutic agents include taxol, cytochalasin B, gramicidin D, ethidium bromide, emetine, mitomycin, etoposide, tenoposide, vincristine, vinblastine, colchicine, doxorubicin, daunorubicin, dihydroxy anthracin dione, mitoxantrone, mithramycin, actinomycin D, 1-dehydrotestosterone, glucocorticoids, procaine, tetracaine, lidocaine, propranolol, puromycin, maytansinoids, e.g., maytansinol (see U.S. Pat. No. 5,208,020), CC-1065 (see U.S. Pat. Nos. 5,475,092, 5,585,499, 5,846, 545) and analogs or homologs thereof. Therapeutic agents include, but are not limited to, antimetabolites (e.g., methotrexate, 6-mercaptopurine, 6-thioguanine, cytarabine, 5-fluorouracil decarbazine), alkylating agents (e.g., mechlorethamine, thioepa chlorambucil, CC-1065, melphalan, carmustine (BSNU) and lomustine (CCNU), cyclothosphamide, busulfan, dibromomannitol, streptozotocin, mitomycin C, and cis-dichlorodiamine platinum (II) (DDP) cisplatin), anthracyclinies (e.g., daunorubicin (formerly daunomycin) and doxorubicin), antibiotics (e.g., dactinomycin (formerly actinomycin), bleomycin, mithramycin, and anthramycin (AMC)), and anti-mitotic agents (e.g., vincristine, vinblastine, taxol and maytansinoids).

In some aspects, this disclosure provides a method of providing a target binding molecule that specifically binds to a TIM-3 receptor. For example, the target binding molecule is an antibody molecule. The method includes: providing a target protein that comprises at least a portion of non-human protein, the portion being homologous to (at least 70, 75, 80, 85, 87, 90, 92, 94, 95, 96, 97, 98, or 99% identical to) a corresponding portion of a human target protein, but differing by at least one amino acid (e.g., at least one, two, three, four, five, six, seven, eight, or nine amino acids); obtaining an antibody molecule that specifically binds to the antigen; and evaluating efficacy of the binding agent in modulating activity of the target protein. The method can further include administering the binding agent (e.g., antibody molecule) or a derivative (e.g., a humanized antibody molecule) to a human subject.

In some embodiments, the anti-TIM-3 antibody molecule interacts with, e.g., binds to, a TIM-3 surface (e.g., one, two, three, five, eight, ten, fifteen, twenty, twenty-one, twenty-five, or more continuous and discontinuous (e.g., noncontiguous) amino acid residues chosen from Val24, Glu25, Tyr26, Phe39, Tyr40, Thr41, Gly56, Ala57, Cys58, Pro59, Val60, Phe61, Ser105, Gly106, Ile107, Asn119, Asp120, Glu121, Lys122, Phe123, Asn124, Leu125, Lys126, Leu127, and/or Val128, e.g., as detailed in Table 13.

In some embodiments, the anti-TIM-3 antibody molecule interacts with, e.g., binds to, a TIM-3 surface (e.g., one, two, three, five, eight, ten, fifteen, twenty, twenty-one, twenty-five, or more continuous or discontinuous (e.g., noncontiguous) amino acid residues chosen from Glu23, Val24, Glu25, Tyr26, Thr41, Pro42, Ala43, Ala44, Pro45, Gly46, Asn47, Leu48, Val49, Pro50, Val51, Cys52, Trp53, Gly54, Lys55, Gly56, Ala57, Cys58, Pro59, Val60, Phe61, Glu121, Lys122, Phe123, Asn124, Leu125, Lys126, and/or Leu127.

In some embodiments, the anti-TIM-3 antibody molecule interacts with, e.g., binds to, a TIM-3 surface (e.g., one, two, three, five, eight, ten, fifteen, twenty, twenty-one, twenty-five, or more continuous or discontinuous (e.g., noncontiguous) amino acid residues chosen from Val24, Glu25, Tyr26, Phe39, Tyr40, Thr41, Pro42, Ala43, Ala44, Pro45, Gly46, Asn47, Leu48, Val49, Pro50, Val51, Cys52, Trp53, Gly54, Lys55, Gly56, Ala57, Cys58, Pro59, Val60, Phe61, Ser105, Gly106, Ile107, Asn119, Asp120, Glu121, Lys122, Phe123, Asn124, Leu125, Lys126, Leu127, and/or Val1128.

In other embodiments, the anti-TIM-3 antibody molecule competes with CEACAM-1 for binding to TIM-3. In one embodiment, the anti-TIM-3 antibody molecule interacts, e.g., binds to, one, two, or more (all) of C58, N119 and K122 of TIM-3, e.g., displaces or competes CEACAM-1 for binding to these residues. In one embodiment, the anti-TIM-3 antibody molecule reduces or blocks the formation of a hydrogen bond between K122 of TIM-3 and N42 of CEACAM-1. With respect to CEACAM-1, it has been shown that CEACAM-1 is a ligand for TIM-3 and is required for its ability to mediate T-cell inhibition, which may have important role in regulating autoimmunity and anti-tumour immunity (Huang, et al. (2014) Nature doi:10.1038/nature13848). Inhibition of an interaction between TIM-3 and CEACAM-1 can be used with the other immunomodulators described herein (e.g., anti-PD-1 inhibitor) to enhance an immune response against a cancer.

In another embodiment, the anti-TIM-3 antibody molecule interacts with, e.g., binds to, a PtdSer-binding loop of TIM-3, e.g., the human TIM-3 IgV domain. In one embodiment, the anti-TIM-3 antibody molecule interacts with, e.g., binds to, at least two PtdSer-binding loops of TIM-3, e.g., the FG loop and CC′ loop of TIM-3 (e.g., a metal ion-dependent ligand binding site (MILIBS)). For example, the carboxyl group of PtdSer can bind to the CC′ loop of TIM-3 and the amino group of PtdSer can bind to the FG loop of TIM-3. In one embodiment, the anti-TIM-3 antibody molecule reduces or prevents PtdSer-mediated membrane penetration of TIM-3 Thus, the anti-TIM-3 antibody molecule may reduce engagement of TIM-3-expressing cells and/or penetration into the membrane of apoptotic cells (which can display PtdSer) for engulfment.

In another embodiment, the anti-TIM-3 antibody molecule competes with HMGB1 for bind to TIM-3. E.g., it reduces binding of HMGB1 to residue 62 of TIM-3 (Q in mouse, E in human TIM-3). With respect to HMGB1, it has been reported to interact with TIM-3 to help tumor-associated dendritic cells suppress nucleic acid-mediated innate immune response (Chiba et al., (2012) Nat. Immunol. 13(9):832-842). Thus, the anti-TIM-3 antibody molecule may enhance nucleic acid-mediated innate immune response.

In yet another embodiment, the anti-TIM-3 antibody molecule does not compete with or reduce a Galectin-9 (Gal-9) ligand to binding to TIM-3.

In embodiments, the anti-TIM-3 antibody molecule is a monospecific antibody molecule or a bispecific antibody molecule.

Pharmaceutical Compositions and Kits

In some aspects, this disclosure provides compositions, e.g., pharmaceutically acceptable compositions, which include an anti-TIM-3 antibody molecule described herein, formulated together with a pharmaceutically acceptable carrier. As used herein, “pharmaceutically acceptable carrier” includes any and all solvents, dispersion media, isotonic and absorption delaying agents, and the like that are physiologically compatible. The carrier can be suitable for intravenous, intramuscular, subcutaneous, parenteral, rectal, spinal or epidermal administration (e.g. by injection or infusion).

The compositions set out herein may be in a variety of forms. These include, for example, liquid, semi-solid and solid dosage forms, such as liquid solutions (e.g., injectable and infusible solutions), dispersions or suspensions, liposomes, and suppositories. A suitable form depends on the intended mode of administration and therapeutic application. Typical suitable compositions are in the form of injectable or infusible solutions. One suitable mode of administration is parenteral (e.g., intravenous, subcutaneous, intraperitoneal, intramuscular). In some embodiments, the antibody molecule is administered by intravenous infusion or injection. In certain embodiments, the antibody is administered by intramuscular or subcutaneous injection.

The phrases “parenteral administration” and “administered parenterally” as used herein means modes of administration other than enteral and topical administration, usually by injection, and includes, without limitation, intravenous, intramuscular, intraarterial, intrathecal, intracapsular, intraorbital, intracardiac, intradermal, intraperitoneal, transtracheal, subcutaneous, subcuticular, intraarticular, subcapsular, subarachnoid, intraspinal, epidural and intrasternal injection and infusion.

Therapeutic compositions typically should be sterile and stable under the conditions of manufacture and storage. The composition can be formulated as a solution, microemulsion, dispersion, liposome, or other ordered structure suitable to high antibody concentration. Sterile injectable solutions can be prepared by incorporating the active compound (i.e., antibody or antibody portion) in the required amount in an appropriate solvent with one or a combination of ingredients enumerated above, as required, followed by filtered sterilization. Generally, dispersions are prepared by incorporating the active compound into a sterile vehicle that contains a basic dispersion medium and the required other ingredients from those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, the preferred methods of preparation are vacuum drying and freeze-drying that yields a powder of the active ingredient plus any additional desired ingredient from a previously sterile-filtered solution thereof. The proper fluidity of a solution can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants. Prolonged absorption of injectable compositions can be brought about by including in the composition an agent that delays absorption, for example, monostearate salts and gelatin.

The antibody molecules can be administered by a variety of methods. Several are known in the art, and for many therapeutic applications, an appropriate route/mode of administration is intravenous injection or infusion. In an embodiment, the antibody molecules can be administered by intravenous infusion at a rate of more than 20 mg/min, e.g., 20-40 mg/min, and preferably greater than or equal to 40 mg/min to reach a dose of about 35 to 440 mg/m², preferably about 70 to 310 mg/m², and more preferably, about 110 to 130 mg/m². In an embodiment, the antibody molecules can be administered by intravenous infusion at a rate of less than 10 mg/min; preferably less than or equal to 5 mg/min to reach a dose of about 1 to 100 mg/m², preferably about 5 to 50 mg/m², about 7 to 25 mg/m² and more preferably, about 10 mg/m². As will be appreciated by the skilled artisan, the route and/or mode of administration will vary depending upon the desired results. In certain embodiments, the active compound may be prepared with a carrier that will protect the compound against rapid release, such as a controlled release formulation, including implants, transdermal patches, and microencapsulated delivery systems. Biodegradable, biocompatible polymers can be used, such as ethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters, and polylactic acid. Many methods for the preparation of such formulations are patented or generally known to those skilled in the art. See, e.g., Sustained and Controlled Release Drug Delivery Systems, J. R. Robinson, ed., Marcel Dekker, Inc., New York, 1978.

In certain embodiments, an antibody molecule can be orally administered, for example, with an inert diluent or an assimilable edible carrier. The antibody molecule (and other ingredients, if desired) may also be enclosed in a hard or soft shell gelatin capsule, compressed into tablets, or incorporated directly into the subject's diet. For oral therapeutic administration, the antibody molecule may be incorporated with excipients and used in the form of ingestible tablets, buccal tablets, troches, capsules, elixirs, suspensions, syrups, wafers, and the like. To administer an antibody molecule by other than parenteral administration, it may be necessary to coat the compound with, or co-administer the compound with, a material to prevent its inactivation. Therapeutic compositions can also be administered with medical devices, and several are known in the art.

Dosage regimens are adjusted to provide the desired response (e.g., a therapeutic response). For example, a single bolus may be administered, several divided doses may be administered over time or the dose may be proportionally reduced or increased as indicated by the exigencies of the therapeutic situation. It is especially advantageous to formulate parenteral compositions in dosage unit form for ease of administration and uniformity of dosage. Dosage unit form as used herein refers to physically discrete units suited as unitary dosages for the subjects to be treated; each unit contains a predetermined quantity of active compound calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. The specification for the dosage unit forms are dictated by and directly dependent on (a) the unique characteristics of the active compound and the particular therapeutic effect to be achieved, and (b) the limitations inherent in the art of compounding such an active compound for the treatment of sensitivity in individuals.

An exemplary, non-limiting range for a therapeutically or prophylactically effective amount of an antibody molecule is 0.1-30 mg/kg, more preferably 1-25 mg/kg. Dosages and therapeutic regimens of the anti-TIM-3 antibody molecule can be determined by a skilled artisan. In certain embodiments, the anti-TIM-3 antibody molecule is administered by injection (e.g., subcutaneously or intravenously) at a dose of about 1 to 40 mg/kg, e.g., 1 to 30 mg/kg, e.g., about 5 to 25 mg/kg, about 10 to 20 mg/kg, about 1 to 5 mg/kg, 1 to 10 mg/kg, 5 to 15 mg/kg, 10 to 20 mg/kg, 15 to 25 mg/kg, or about 3 mg/kg.

A “therapeutically effective amount” refers to an amount effective, at dosages and for periods of time necessary, to achieve the desired therapeutic result. A therapeutically effective amount of the modified antibody or antibody fragment may vary according to factors such as the disease state, age, sex, and weight of the individual, and the ability of the antibody or antibody portion to elicit a desired response in the individual. A therapeutically effective amount is also one in which any toxic or detrimental effects of the antibody molecule is outweighed by the therapeutically beneficial effects. A “therapeutically effective dosage” preferably inhibits a measurable parameter by at least about 20%, more preferably by at least about 40%, even more preferably by at least about 60%, and still more preferably by at least about 80% relative to untreated subjects. The measurable parameter may be, e.g., tumor growth rate or pathogen growth rate. The ability of a compound to inhibit a measurable parameter can be evaluated in an animal model system predictive of efficacy in the corresponding human disease. Alternatively, this property of a composition can be evaluated by examining the ability of the compound to inhibit, such inhibition in vitro by assays known to the skilled practitioner.

A “prophylactically effective amount” refers to an amount effective, at dosages and for periods of time necessary, to achieve the desired prophylactic result. Typically, since a prophylactic dose is used in subjects prior to or at an earlier stage of disease, the prophylactically effective amount will be less than the therapeutically effective amount.

Also within this disclosure is a kit comprising an antibody molecule described herein. The kit can include one or more other elements including: instructions for use; other reagents, e.g., a label, a therapeutic agent, or an agent useful for chelating, or otherwise coupling, an antibody to a label or therapeutic agent, or a radioprotective composition; devices or other materials for preparing the antibody molecule for administration; pharmaceutically acceptable carriers; and devices or other materials for administration to a subject.

Uses of Anti-TIM-3 Antibody Molecules

TIM-3 is a coinhibitory protein expressed, e.g., on activated T helper 1 (Th1) CD4+ and cytotoxic CD8+ T cells that secrete IFN-γ. TIM-3 is largely co-expressed on PD-1+ exhausted T cells as shown in preclinical models of cancer and viral exhaustion. Co-blockade of these pathways can restore effector T cell function (e.g., IFN-γ secretion, proliferation) in several models as well as human PBMCs derived from metastatic melanoma patients and patients with HIV or HCV. TIM-3 is also enriched on Fox-P3+ natural regulatory T cells (and FoxP3-negative induced regulatory cells), and the nTreg expression correlates with disease severity in NSCLC, hepatocellular and ovarian carcinoma. In mouse models, TIM-3+ nTregs have been shown to be more immunosuppressive (secrete higher levels of IL-10 and TGF-β).

In addition, TIM-3 can play an important role on innate immune cells, including NK cells, monocytes/macrophages and dendritic cells (DCs). TIM-3 is constitutively expressed on macrophages and DCs, and blockade can enhance TNF-α secretion from human monocytes and increase NF-κB expression in a mouse dendritic cell line. TIM-3 can also contribute to expansion of myeloid-derived suppressor cells (MDSCs). Constitutive expression of TIM-3 on macrophages is associated with less IL-12 secretion, and downregulation of TIM-3 post-TLR activation can lead to enhanced IL-12 and subsequent effector T cell responses.

The antibody molecules disclosed herein have in vitro and in vivo diagnostic, as well as therapeutic and prophylactic utilities. In some embodiments, the antibody molecules modulate (e.g., enhance or inhibit) an immune response in a subject by binding TIM-3. For example, these molecules can be administered to cells in culture, in vitro or ex vivo, or to a subject, e.g., a human subject, e.g., in vivo, to modulate (e.g., enhance or inhibit) immunity.

Accordingly, in some aspects, the disclosure provides a method of modifying an immune response in a subject comprising administering to the subject an antibody molecule described herein, such that the immune response in the subject is modified. In some embodiments, the immune response is enhanced, stimulated or up-regulated. In certain embodiments, the immune response is inhibited or downregulated. For example, these antibody molecules can be administered to cells in culture, e.g. in vitro or ex vivo, or in a subject, e.g., in vivo, to treat, prevent, and/or diagnose a variety of disorders, such as cancers, immune disorders, and infectious diseases.

As used herein, the term “subject” is intended to include human and non-human animals. In some embodiments, the subject is a human subject, e.g., a human patient having a disorder or condition characterized by abnormal TIM-3 functioning. Generally, the subject has at least some TIM-3 protein, including the TIM-3 epitope that is bound by the antibody molecule, e.g., a high enough level of the protein and epitope to support antibody binding to TIM-3. The term “non-human animals” includes mammals and non-mammals, such as non-human primates. In some embodiments, the subject is a human. In some embodiments, the subject is a human patient in need of enhancement of an immune response. The methods and compositions described herein are suitable for treating human patients having a disorder that can be treated by modulating (e.g., augmenting or inhibiting) an immune response.

Methods of Treating Immune Disorders

TIM-3 is a transmembrane receptor expressed on T cells, e.g., CD4+ T cells, CD8+ T cells, regulatory T cells, and differentiated Th1 cells. TIM-3-dependent trafficking of Th1 cells to target tissue can be inhibited with soluble TIM-3 (see U.S. Pat. No. 7,470,428). Accordingly, modulating TIM-3 function may reduce T-cell trafficking into a target tissue, e.g., in subjects with autoimmune disease. TIM-3 may play an important role in the induction of autoimmune diseases by regulating macrophage activation and/or function. Accordingly, in certain embodiments, the anti-TIM-3 antibody molecules described herein are suitable for use in downregulating an unwanted immune response, e.g., treating autoimmune diseases.

Furthermore, as described in the Examples herein, anti-TIM-3 antibodies can stimulate NK cell-mediated killing of target cells, and can enhance IFN-gamma secretion and proliferation of CD4+ T cells. Accordingly, in certain embodiments, the anti-TIM-3 antibody molecules described herein are suitable for use in stimulating a desired immune response, e.g., an immune response against a cancer cell or pathogen.

The anti-TIM-3 antibodies described herein may be used for treating immune disorders, especially T lymphocyte-related disorders, including, but not limited to, chronic inflammatory diseases and disorders, such as Crohn's disease, reactive arthritis, including Lyme disease, insulin-dependent diabetes, organ-specific autoimmunity, including multiple sclerosis, Hashimoto's thyroiditis and Grave's disease, contact dermatitis, psoriasis, graft rejection, graft versus host disease, sarcoidosis, atopic conditions, such as asthma and allergy, including allergic rhinitis, gastrointestinal allergies, including food allergies, eosinophilia, conjunctivitis, glomerular nephritis (e.g., IgA nephropathy), certain pathogen susceptibilities such as helminthic (e.g., leishmaniasis).

In certain embodiments, the anti-TIM-3 antibody is used to modulate T cell function, e.g., CD4+ T cells, CD8+ T cells, Tregs, Th17, and Th1 function. In some embodiments, the anti-TIM-3 antibody molecule causes TIM-3 blockade, and is used to treat an immune disorder which is not a Th1-dependent disease (see Schroll et al., Am J Pathol 2010 April; 176(4):1716-1742). In certain embodiments, the anti-TIM-3 antibody molecule does not cause TIM-3 blockade.

In some aspects, the present disclosure provides methods of administering an anti-TIM-3 antibody molecule, resulting in promoting or reducing T-cell trafficking to a target tissue, promoting or inhibiting antigen-presenting cell (APC) activation.

In some embodiments the subject is in need of treatment for an autoimmune disease. Autoimmune disease include those in which a subject's own antibodies react with host tissue or in which immune effector T cells are autoreactive to endogenous self-peptides and cause destruction of tissue. Thus an immune response is mounted against a subject's own antigens, referred to as self-antigens. Autoimmune diseases include but are not limited to rheumatoid arthritis, Crohn's disease e.g., pediatric Crohn's disease, multiple sclerosis, systemic lupus erythematosus (SLE), autoimmune encephalomyelitis, myasthenia gravis (MG), Hashimoto's thyroiditis, Goodpasture's syndrome, pemphigus (e.g., pemphigus vulgaris), Grave's disease, autoimmune hemolytic anemia, autoimmune thrombocytopenic purpura, scleroderma with anti-collagen antibodies, mixed connective tissue disease, polymyositis, pernicious anemia, idiopathic Addison's disease, autoimmune-associated infertility, glomerulonephritis (e.g., crescentic glomerulonephritis, proliferative glomerulonephritis), bullous pemphigoid, Sjogren's syndrome, insulin resistance, autoimmune diabetes mellitus (type 1 diabetes mellitus; insulin-dependent diabetes mellitus), atherosclerosis, and Alzheimer's disease.

In some aspects, an anti-TIM-3 antibody molecule described herein is administered to treat an unwanted immune response to an allergen. Examples of natural animal and plant allergens include proteins specific to the following genuses: Canine (Canis familiaris); Dermatophagoides (e.g., Dermatophagoides farinae); Felis (Felis domesticus); Ambrosia (Ambrosia artemiisfolia; Lolium (e.g., Lolium perenne or Lolium multiflorum); Cryptomeria (Cryptomeria japonica); Alternaria (Alternaria alternata); Alder; Alnus (Alnus gultinosa); Betula (Betula verrucosa); Quercus (Quercus alba); Olea (Olea europa); Artemisia (Artemisia vulgaris); Plantago (e.g., Plantago lanceolata); Parietaria (e.g., Parietaria officinalis or Parietaria judaica); Blattella (e.g., Blattella germanica); Apis (e.g., Apis multiflorum); Cupressus (e.g., Cupressus sempervirens, Cupressus arizonica and Cupressus macrocarpa); Juniperus (e.g., Juniperus sabinoides, Juniperus virginiana, Juniperus communis and Juniperus ashei); Thuya (e.g., Thuya orientalis); Chamaecyparis (e.g., Chamaecyparis obtusa); Periplaneta (e.g., Periplaneta americana); Agropyron (e.g., Agropyron repens); Secale (e.g., Secale cereale); Triticum (e.g., Triticum aestivum); Dactylis (e.g., Dactylis glomerata); Festuca (e.g., Festuca elatior); Poa (e.g., Poa pratensis or Poa compressa); Avena (e.g., Avena sativa); Holcus (e.g., Holcus lanatus); Anthoxanthum (e.g., Anthoxanthum odoratum); Arrhenatherum (e.g., Arrhenatherum elatius); Agrostis (e.g., Agrostis alba); Phleum (e.g., Phleum pratense); Phalaris (e.g., Phalaris arundinacea); Paspalum (e.g., Paspalum notatum); Sorghum (e.g., Sorghum halepensis); and Bromus (e.g., Bromus inermis).

In some embodiments, the anti-TIM-3 antibody molecule is administered to treat multiple sclerosis, Crohn's disease, sepsis, SIRS (Systemic Inflammatory Response Syndrome), or glomerulonephritis.

Methods of Treating Cancer

In some aspects, the present disclosure provides methods of administering an anti-TIM-3 antibody molecule to treat cancer. While not wishing to be bound by theory, in some embodiments, an anti-TIM-3 antibody molecule stimulates a patient's immune system to recognize and destroy cancer cells, thereby treating the cancer. In some embodiments, the cancer to be treated expresses TIM-3, and the anti-TIM-3 antibody molecule targets the cancer cells or cells in the cancer microenvironment.

In some aspects, the present disclosure relates to treatment of a subject in vivo using an anti-TIM-3 antibody molecule such that growth of cancerous tumors is inhibited. An anti-TIM-3 antibody may be used alone to inhibit the growth of cancerous tumors. Alternatively, an anti-TIM-3 antibody may be used in combination with one or more of: a standard cancer treatment (e.g., for cancer or infectious disorders), or another antibody or antigen-binding fragment thereof, an immunomodulator (e.g., an activator of a costimulatory molecule or an inhibitor of an inhibitory molecule); a vaccine, (e.g., a cancer vaccine); or other forms of cellular immunotherapy, as described below.

Accordingly, in some embodiments, the disclosure provides a method of inhibiting growth of tumor cells in a subject, comprising administering to the subject a therapeutically effective amount of an anti-TIM-3 antibody molecule described herein.

In some embodiments, the methods are suitable for the treatment of cancer in vivo. To achieve antigen-specific enhancement of immunity, the anti-TIM-3 antibody molecule can be administered together with an antigen of interest. When antibodies to TIM-3 are administered in combination with one or more agents, the combination can be administered in either order or simultaneously.

Types of Cancer

In certain aspects, a method of treating a subject, e.g., reducing or ameliorating, a hyperproliferative condition or disorder (e.g., a cancer), e.g., solid tumor, a hematological cancer, a soft tissue tumor, or a metastatic lesion, in a subject is provided. The method includes administering to the subject one or more anti-TIM-3 antibody molecules described herein, alone or in combination with other agents or therapeutic modalities.

As used herein, the term “cancer” is meant to include all types of cancerous growths or oncogenic processes, metastatic tissues or malignantly transformed cells, tissues, or organs, irrespective of histopathologic type or stage of invasiveness. Examples of cancerous disorders include, but are not limited to, solid tumors, hematological cancers, soft tissue tumors, and metastatic lesions. Examples of solid tumors include malignancies, e.g., sarcomas, and carcinomas (including adenocarcinomas and squamous cell carcinomas) of the various organ systems, such as those affecting liver, lung, breast, lymphoid, gastrointestinal (e.g., colon), genitourinary tract (e.g., renal, urothelial cells), prostate and pharynx. Adenocarcinomas include malignancies such as most colon cancers, rectal cancer, renal-cell carcinoma, liver cancer, non-small cell carcinoma of the lung, cancer of the small intestine and cancer of the esophagus. Squamous cell carcinomas include malignancies, e.g., in the lung, esophagus, skin, head and neck region, oral cavity, anus, and cervix. In one embodiment, the cancer is a melanoma, e.g., an advanced stage melanoma. Metastatic lesions of the aforementioned cancers can also be treated or prevented using the methods and compositions described herein.

Exemplary cancers whose growth can be inhibited using the antibody molecules disclosed herein include cancers typically responsive to immunotherapy. Non-limiting examples of suitable cancers for treatment include melanoma (e.g., metastatic malignant melanoma), renal cancer (e.g. clear cell carcinoma), prostate cancer (e.g. hormone refractory prostate adenocarcinoma), breast cancer, colon cancer and lung cancer (e.g. non-small cell lung cancer). Additionally, refractory or recurrent malignancies can be treated using the antibody molecules described herein.

Cancers include, but are not limited to, basal cell carcinoma, biliary tract cancer; bladder cancer; bone cancer; brain and CNS cancer; primary CNS lymphoma; neoplasm of the central nervous system (CNS); breast cancer; cervical cancer; choriocarcinoma; colon and rectum cancer; connective tissue cancer; cancer of the digestive system; endometrial cancer; esophageal cancer; eye cancer; cancer of the head and neck; gastric cancer; intra-epithelial neoplasm; kidney cancer; larynx cancer; leukemia (including acute myeloid leukemia, chronic myeloid leukemia, acute lymphoblastic leukemia, chronic lymphocytic leukemia, chronic or acute leukemias); liver cancer; lung cancer (e.g., small cell and non-small cell); lymphoma including Hodgkin's and non-Hodgkin's lymphoma; lymphocytic lymphoma; melanoma, e.g., cutaneous or intraocular malignant melanoma; myeloma; neuroblastoma; oral cavity cancer (e.g., lip, tongue, mouth, and pharynx); ovarian cancer; pancreatic cancer; prostate cancer; retinoblastoma; rhabdomyosarcoma; rectal cancer; cancer of the respiratory system; sarcoma; skin cancer; stomach cancer; testicular cancer; thyroid cancer; uterine cancer; cancer of the urinary system, hepatocarcinoma, cancer of the anal region, carcinoma of the fallopian tubes, carcinoma of the vagina, carcinoma of the vulva, cancer of the small intestine, cancer of the endocrine system, cancer of the parathyroid gland, cancer of the adrenal gland, sarcoma of soft tissue, cancer of the urethra, cancer of the penis, solid tumors of childhood, spinal axis tumor, brain stem glioma, pituitary adenoma, Kaposi's sarcoma, epidermoid cancer, squamous cell cancer, T-cell lymphoma, environmentally induced cancers including those induced by asbestos, as well as other carcinomas and sarcomas, and combinations of said cancers.

In some embodiments, the cancer treated with the antibody molecules, includes but is not limited to, solid tumors, hematological cancers, soft tissue tumors, and metastatic lesions. Examples of solid tumors include malignancies, e.g., sarcomas, adenocarcinomas, and carcinomas, of the various organ systems, such as those affecting lung, breast, lymphoid, gastrointestinal (e.g., colon), genitals and genitourinary tract (e.g., renal, urothelial, bladder cells), pharynx, CNS (e.g., brain, neural or glial cells), skin (e.g., melanoma), and pancreas, as well as adenocarcinomas which include malignancies such as most colon cancers, rectal cancer, renal-cell carcinoma, liver cancer, non-small cell-carcinoma of the lung, cancer of the small intestine and cancer of the esophagus. Methods and compositions disclosed herein are also useful for treating metastatic lesions associated with the aforementioned cancers.

While not wishing to be bound by theory, in some embodiments, a patient is more likely to respond to treatment with an immunomodulator (optionally in combination with one or more agents as described herein) if the patient has a cancer that highly expresses PD-L1, and/or the cancer is infiltrated by anti-tumor immune cells, e.g., TILs. The anti-tumor immunce cells may be positive for CD8, PD-L1, and/or IFN-γ; thus levels of CD8, PD-L1, and/or IFN-γ can serve as a readout for levels of TILs in the microenvironment. In certain embodiments, the cancer microenvironment is referred to as triple-positive for PD-L1/CD8/IFN-γ.

Accordingly, in certain aspects, this application provides methods of determining whether a tumor sample is positive for one or more of PD-L1, CD8, and IFN-γ, and if the tumor sample is positive for one or more, e.g., two, or all three, of the markers, then administering to the patient a therapeutically effective amount of an anti-PD-1 antibody molecule, optionally in combination with one or more other immunomodulators or anti-cancer agents, e.g., an anti-TIM3 antibody as described herein.

In the following indications, a large fraction of patients are triple-positive for PD-L1/CD8/IFN-γ: Lung cancer (squamous); lung cancer (adenocarcinoma); head and neck cancer; stomach cancer; NSCLC; HNSCC; gastric cancers (e.g., MSIhi and/or EBV+); CRC (e.g., MSIhi); nasopharyngeal cancer (NPC); cervical cancer (e.g., squamous); thyroid cancer e.g., papillary thyroid; melanoma; TN breast cancer; and DLBCL (Diffuse Large B-Cell Lymphoma). In breast cancer generally and in colon cancer generally, a moderate fraction of patients is triple-positive for PD-L1/CD8/IFN-γ. In the following indications, a small fraction of patients are triple-positive for PD-L1/CD8/IFN-γ: ER+ breast cancer, and pancreatic cancer. These findings are discussed further in Example 9. Regardless of whether a large or small fraction of patients is triple-positive for these markers, screening the patients for these markers allows one to identify a fraction of patients that has an especially high likelihood of responding favorably to therapy with a PD-1 antibody (e.g., a blocking PD-1 antibody), optionally in combination with one or more other immunomodulators (e.g., an anti-TIM-3 antibody molecule described herein, an anti-LAG-3 antibody molecule, or an anti-PD-L1 antibody molecule) and/or anti-cancer agents, e.g., those listed in Table 6 and disclosed in the publications listed in Table 6.

In some embodiments, the cancer sample is classified as triple-positive for PDL1/CD8/IFN-γ. This measurement can roughly be broken down into two thresholds: whether an individual cell is classified as positive, and whether the sample as a whole is classified as positive. First, one can measure, within an individual cell, the level of PD-L1, CD8, and/or IFN-γ. In some embodiments, a cell that is positive for one or more of these markers is a cell that has a higher level of the marker compared to a control cell or a reference value. For example, in some embodiments, a high level of PD-L1 in a given cell is a level higher than the level of PD-L1 in a corresponding non-cancerous tissue in the patient. As another example, in some embodiments, a high level of CD8 or IFN-γ in a given cell is a level of that protein typically seen in a TIL. Second, one can also measure the percentage of cells in the sample that are positive for PD-L, CD8, and/or IFN-γ. (It is not necessary for a single cell to express all three markers.) In some embodiments, a triple positive sample is one that has a high percentage of cells, e.g., higher than a reference value or higher than a control sample, that are positive for these markers.

In other embodiments, one can measure the levels of PDL1, CD8, and/or IFN-γ overall in the sample. In this case, a high level of CD8 or IFN-γ in the sample can be the level of that protein typically seen in a tumor infiltrated with TIL. Similarly, a high level of PD-L1 can be the level of that protein typically seen in a tumor sample, e.g., a tumor microenvironment.

The identification of subsets of patients that are triple-positive for PD-L1/CD8/IFN-γ, as shown in Example 10 herein, reveals certain sub-populations of patients that are likely to be especially responsive to PD-1 antibody therapy. For instance, many IM-TN (immunomodulatory, triple negative) breast cancer patients are triple-positive for PDL1/CD8/IFN-γ. IM-TN breast cancer is described in, e.g., Brian D. Lehmann et al., “Identification of human triple-negative breast cancer subtypes and preclinical models for selection of targeted therapies”, J Clin Invest. Jul. 1, 2011; 121(7): 2750-2767. Triple-negative breast cancers are those that do not express estrogen receptor (ER), progesterone receptor (PR) and Her2/neu. These cancers are difficult to treat because they are typically not responsive to agents that target ER, PR, and Her2/neu. Triple-negative breast cancers can be further subdivided into different classes, one of which is immunomodulatory. As described in Lehmann et al., IM-TN breast cancer is enriched for factors involved in immune cell processes, for example, one or more of immune cell signaling (e.g., TH1/TH2 pathway, NK cell pathway, B cell receptor signaling pathway, DC pathway, and T cell receptor signaling), cytokine signaling (e.g., cytokine pathway, IL-12 pathway, and IL-7 pathway), antigen processing and presentation, signaling through core immune signal transduction pathways (e.g., NFKB, TNF, and JAK/STAT signaling), genes involved in T-cell function, immune transcription, interferon (IFN) response and antigen processing. Accordingly, in some embodiments, the cancer treated is a cancer that is, or is determined to be, positive for one or more marker of IM-TN breast cancer, e.g., a factor that promotes one or more of immune cell signaling (e.g., TH1/TH2 pathway, NK cell pathway, B cell receptor signaling pathway, DC pathway, and T cell receptor signaling), cytokine signaling (e.g., cytokine pathway, IL-12 pathway, and IL-7 pathway), antigen processing and presentation, signaling through core immune signal transduction pathways (e.g., NFKB, TNF, and JAK/STAT signaling), genes involved in T-cell function, immune transcription, interferon (IFN) response and antigen processing.

As another example, it is shown herein that a subset of colon cancer patients having high MSI (microsatellite instability) is also triple-positive for PD-L1/CD8/IFN-γ. Accordingly, in some embodiments, a PD-1 antibody, optionally in combination with one or more immunomodulators such as a TIM-3 antibody described herein, a LAG-3 antibody, or PD-L1 antibody, and one or more anti-cancer agents, e.g., an anti-cancer agent described in Table 6 or in a publication in Table 6, is administered to a patient who has, or who is identified as having, colon cancer with high MSI, thereby treating the cancer. In some embodiments, a cell with high MSI is a cell having MSI at a level higher than a reference value or a control cell, e.g., a non-cancerous cell of the same tissue type as the cancer.

As another example, it is shown herein that a subset of gastric cancer patients having high MSI, and/or which is EBV+, is also triple-positive for PD-L1/CD8/IFN-γ. Accordingly, in some embodiments, a PD-1 antibody, optionally in combination with one or more immunomodulators such as a TIM-3 antibody described herein, a LAG-3 antibody, or PD-L1 antibody, and one or more anti-cancer agents, e.g., an anti-cancer agent described in Table 6 or in a publication in Table 6 is administered to a patient who has, or who is identified as having, gastric cancer with high MSI and/or EBV+, thereby treating the cancer. In some embodiments, a cell with high MSI is a cell having MSI at a level higher than a reference value or a control cell, e.g., a non-cancerous cell of the same tissue type as the cancer.

Additionally disclosed herein are methods of assaying a cancer for PD-L1, and then treating the cancer with a PD-1 antibody, optionally in combination with one or more immunomodulators such as a TIM-3 antibody described herein, a LAG-3 antibody, or PD-L1 antibody. As described in Example 10 herein, a cancer sample can be assayed for PD-L1 protein levels or mRNA levels. A sample having levels of PD-L1 (protein or mRNA) higher than a reference value or a control cell (e.g., a non-cancerous cell) can be classified as PD-L1 positive. Accordingly, in some embodiments, a PD-1 antibody (optionally in combination with one or more anti-cancer agents, optionally in combination with one or more immunomodulators such as a TIM-3 antibody described herein, a LAG-3 antibody, or PD-L1 antibody) is administered to a patient who has, or who is identified as having, a cancer that is PD-L1 positive. The cancer may be, e.g., non-small cell lung (NSCLC) adenocarcinoma (ACA), NSCLC squamous cell carcinoma (SCC), or hepatocellular carcinoma (HCC).

Based on, e.g, Example 9 herein, it was found that certain gastric cancers that are triple-positive for PDL1/CD8/IFN-γ are also positive for PIK3CA. Accordingly, in some embodiments, a cancer can be treated with an anti-PD-1 antibody molecule (optionally in combination with one or more immunomodulators, e.g., an anti-LAG-3 antibody molecule, an anti-TIM-3 antibody molecule as described herein, or an anti-PD-L1 antibody molecule) and an agent that inhibits PIK3CA. Exemplary agents in this category are described in Stein R C (September 2001). “Prospects for phosphoinositide 3-kinase inhibition as a cancer treatment”. Endocrine-related Cancer 8 (3): 237-48 and Marone R, Cmiljanovic V, Giese B, Wymann M P (January 2008). “Targeting phosphoinositide 3-kinase: moving towards therapy”. Biochimica et Biophysica Acta 1784 (1): 159-85.

Based on, e.g, Example 9 herein, CRC, e.g., a patient that has (or is identified as having) MSI-high CRC may be treated with a PD-1 antibody, optionally in combination with a therapeutic that targets one or more of TIM-3, e.g., anti-TIM-3 antibody described herein, LAG-3, RNF43, and BRAF. For instance, these cancers may be treated with a PD-1 antibody, optionally in combination with one or more therapeutics that target one or more of TIM-3, LAG-3, PD-1, RNF43, and BRAF. In embodiments, the one or more therapeutics include an immunomodulators such as an anti-TIM-3 antibody described herein, an anti-LAG-3 antibody molecule, and an anti-cancer agent described in Table 6 or a publication listed in Table 6. LAG-3 inhibitors, e.g., antibodies, are described herein. RNF43 can be inhibited, e.g., with an antibody, small molecule (e.g., 2-(2′,3-dimethyl-[2,4′-bipyridin]-5-yl)-N-(5-(pyrazin-2-yl)pyridin-2-yl)acetamide (Compound A28)), siRNA, or a Rspo ligand or derivative thereof. BRAF inhibitors (e.g., vemurafenib or dabrafenib) are described herein.

Based on, e.g, Example 9 herein, a patient that has (or is identified as having) a squamous cell lung cancer may be treated with a PD-1 antibody molecule in combination with a therapeutic that targets TIM-3, e.g., a TIM-3 antibody molecule, LAG-3, e.g., a LAG-3 antibody molecule, and optionally with one or more anti-cancer agents, e.g., an anti-cancer agent described in Table 6 or in a publication in Table 6.

In some embodiments, a subject that has (or is identified as having) a squamous cell lung cancer may be treated with a PD-1 antibody, optionally in combination with a therapeutic that targets TIM-3, e.g., a TIM-3 antibody described herein.

Based on, e.g, Example 9 herein, a patient that has (or is identified as having) a thyroid cancer may be treated with a PD-1 antibody molecule, optionally in combination with a therapeutic that targets BRAF, and optionally in combination with one or more immunomodulators, e.g., an anti-LAG-3 antibody molecule, an anti-TIM-3 antibody molecule described herein, and an anti-PD-L1 antibody molecule. BRAF inhibitors (e.g., vemurafenib or dabrafenib) are described herein, e.g., in Table 6 and the publications listed in Table 6.

In other embodiments, the cancer is a hematological malignancy or cancer including but is not limited to a leukemia or a lymphoma. For example, a anti-TIM-3 antibody molecule can be used to treat cancers and malignancies including, but not limited to, e.g., acute leukemias including but not limited to, e.g., B-cell acute lymphoid leukemia (“BALL”), T-cell acute lymphoid leukemia (“TALL”), acute lymphoid leukemia (ALL); one or more chronic leukemias including but not limited to, e.g., chronic myelogenous leukemia (CML), chronic lymphocytic leukemia (CLL); additional hematologic cancers or hematologic conditions including, but not limited to, e.g., B cell prolymphocytic leukemia, blastic plasmacytoid dendritic cell neoplasm, Burkitt's lymphoma, diffuse large B cell lymphoma, Follicular lymphoma, Hairy cell leukemia, small cell- or a large cell-follicular lymphoma, malignant lymphoproliferative conditions, MALT lymphoma, mantle cell lymphoma, Marginal zone lymphoma, multiple myeloma, myelodysplasia and myelodysplastic syndrome, non-Hodgkin's lymphoma, plasmablastic lymphoma, plasmacytoid dendritic cell neoplasm, Waldenstrom macroglobulinemia, and “preleukemia” which are a diverse collection of hematological conditions united by ineffective production (or dysplasia) of myeloid blood cells, and the like.

In some embodiments, the anti-TIM-3 antibody molecule is used to treat a cancer that expresses TIM-3. TIM-3-expressing cancers include cervical cancer (Cao et al., PLoS One. 2013; 8(1):e53834), lung cancer (Zhuang et al., Am J Clin Pathol. 2012; 137(6):978-985) (e.g., non-small cell lung cancer), acute myeloid leukemia (Kikushige et al., Cell Stem Cell. 2010 Dec. 3; 7(6):708-17), diffuse large B cell lymphoma, melanoma (Fourcade et al., JEM 2010; 207 (10): 2175), renal cancer (e.g., renal cell carcinoma (RCC), e.g., kidney clear cell carcinoma, kidney papillary cell carcinoma, or metastatic renal cell carcinoma), squamous cell carcinoma, esophageal squamous cell carcinoma, nasopharyngeal carcinoma, colorectal cancer, breast cancer (e.g., a breast cancer that does not express one, two or all of estrogen receptor, progesterone receptor, or Her2/neu, e.g., a triple negative breast cancer), mesothelioma, hepatocellular carcinoma, and ovarian cancer. The TIM-3-expressing cancer may be a metastatic cancer. In other embodiments, the anti-TIM-3 antibody molecule is used to treat a cancer that is characterized by macrophage activity or high expression of macrophage cell markers. In an embodiment, the anti-TIM-3 antibody molecule is used to treat a cancer that is characterized by high expression of one or more of the following macrophage cell markers: LILRB4 (macrophage inhibitory receptor), CD14, CD16, CD68, MSR1, SIGLEC1, TREM2, CD163, ITGAX, ITGAM, CD11b, or CD11c.

Combination of Anti-TIM-3 Antibodies with Cancer Vaccines

Antibody molecules to TIM-3 can be combined with an immunogenic agent, such as cancerous cells, purified tumor antigens (including recombinant proteins, peptides, and carbohydrate molecules), cells, and cells transfected with genes encoding immune stimulating cytokines (He et al (2004) J. Immunol. 173:4919-28). Non-limiting examples of tumor vaccines that can be used include peptides of melanoma antigens, such as peptides of gp100, MAGE antigens, Trp-2, MART1 and/or tyrosinase, or tumor cells transfected to express the cytokine GM-CSF, DNA-based vaccines, RNA-based vaccines, and viral transduction-based vaccines. The cancer vaccine may be prophylactic or therapeutic.

In some embodiments, therapy with an anti-TIM-3 antibody molecule is combined with a vaccination protocol. Many experimental strategies for vaccination against tumors have been devised (see Rosenberg, S., 2000, Development of Cancer Vaccines, ASCO Educational Book Spring: 60-62; Logothetis, C., 2000, ASCO Educational Book Spring: 300-302; Khayat, D. 2000, ASCO Educational Book Spring: 414-428; Foon, K. 2000, ASCO Educational Book Spring: 730-738; see also Restifo, N. and Sznol, M., Cancer Vaccines, Ch. 61, pp. 3023-3043 in DeVita, V. et al. (eds.), 1997, Cancer: Principles and Practice of Oncology. Fifth Edition). In one of these strategies, a vaccine is prepared using autologous or allogeneic tumor cells. These cellular vaccines have been shown to be most effective when the tumor cells are transduced to express GM-CSF. GM-CSF has been shown to be a potent activator of antigen presentation for tumor vaccination (Dranoff et al. (1993) Proc. Natl. Acad. Sci. U.S.A. 90: 3539-43).

Anti-TIM-3 antibody molecules can be used in conjunction with a collection of recombinant proteins and/or peptides expressed in a tumor in order to generate an immune response to these proteins. These proteins are normally viewed by the immune system as self antigens and are therefore tolerant to them. The tumor antigen may also include the protein telomerase, which is required for the synthesis of telomeres of chromosomes and which is expressed in more than 85% of human cancers and in only a limited number of somatic tissues (Kim, N et al. (1994) Science 266: 2011-2013). (These somatic tissues may be protected from immune attack by various means). Tumor antigens may also be “neo-antigens” expressed in cancer cells because of somatic mutations that alter protein sequence or create fusion proteins between two unrelated sequences (e.g., bcr-abl in the Philadelphia chromosome), or idiotype from B cell tumors.

Other tumor vaccines may include the proteins from viruses implicated in human cancers such a Human Papilloma Viruses (HPV), Hepatitis Viruses (HBV and HCV) and Kaposi's Herpes Sarcoma Virus (KHSV), and Epstein-Barr virus (EBV). Another form of tumor specific antigen which may be used in conjunction with an anti-TIM-3 antibody is purified heat shock proteins (HSP) isolated from the tumor tissue itself. These heat shock proteins contain fragments of proteins from the tumor cells and these HSPs are highly efficient at delivery to antigen presenting cells for eliciting tumor immunity (Suot, R & Srivastava, P (1995) Science 269:1585-1588; Tamura, Y. et al. (1997) Science 278:117-120).

Dendritic cells (DC) are potent antigen presenting cells that can be used to prime antigen-specific responses. DC's can be produced ex vivo and loaded with various protein and peptide antigens as well as tumor cell extracts (Nestle, F. et al. (1998) Nature Medicine 4: 328-332). DCs may also be transduced by genetic means to express these tumor antigens as well. DCs have also been fused directly to tumor cells for the purposes of immunization (Kugler, A. et al. (2000) Nature Medicine 6:332-336). As a method of vaccination, DC immunization may be effectively combined with an anti-TIM-3 therapy to activate more potent anti-tumor responses.

Alternatively or in combination, the combination further includes an inhibitor or activator of an immune checkpoint modulator, e.g., a LAG-3 inhibitor (e.g., an anti-TIM-3 antibody molecule), a PD-L1 inhibitor (e.g., an anti-PD-L1 antibody molecule), a PD-1 inhibitor (e.g., an anti-PD-1 antibody molecule), or a CTLA-4 inhibitor (e.g., an anti-CTLA-4 antibody), or any combination thereof.

TIM-3 blockade may also be combined with a standard cancer treatment. TIM-3 blockade may be effectively combined with chemotherapeutic regimes. In these instances, it may be possible to reduce the dose of chemotherapeutic reagent administered (Mokyr, M. et al. (1998) Cancer Research 58: 5301-5304). In certain embodiments, the methods and compositions described herein are administered in combination with one or more of other antibody molecules, chemotherapy, other anti-cancer therapy (e.g., targeted anti-cancer therapies, or oncolytic drugs), cytotoxic agents, immune-based therapies (e.g., cytokines), surgical and/or radiation procedures. Exemplary cytotoxic agents that can be administered in combination with include antimicrotubule agents, topoisomerase inhibitors, anti-metabolites, mitotic inhibitors, alkylating agents, anthracyclines, vinca alkaloids, intercalating agents, agents capable of interfering with a signal transduction pathway, agents that promote apoptosis, proteosome inhibitors, and radiation (e.g., local or whole body irradiation).

Alternatively, or in combination with the aforesaid combinations, the methods and compositions described herein can be administered in combination with one or more of: an immunomodulator (e.g., an activator of a costimulatory molecule or an inhibitor of an inhibitory molecule); a vaccine, e.g., a therapeutic cancer vaccine; or other forms of cellular immunotherapy.

Exemplary non-limiting combinations and uses of the anti-TIM-3 antibody molecules include the following.

In certain embodiments, the anti-TIM-3 antibody molecule is administered in combination with a modulator of a costimulatory molecule or an inhibitory molecule, e.g., a coinhibitory ligand or receptor.

In one embodiment, the anti-TIM-3 antibody molecule is administered in combination with a modulator, e.g., agonist, of a costimulatory molecule. In one embodiment, the agonist of the costimulatory molecule is chosen from an agonist (e.g., an agonistic antibody or antigen-binding fragment thereof, or soluble fusion) of OX40, CD2, CD27, CDS, ICAM-1, LFA-1 (CD11a/CD18), ICOS (CD278), 4-1BB (CD137), GITR, CD30, CD40, BAFFR, HVEM, CD7, LIGHT, NKG2C, SLAMF7, NKp80, CD160, B7-H3 or CD83 ligand.

In another embodiment, the anti-TIM-3 antibody molecule is used in combination with a costimulatory molecule, e.g., an agonist associated with a positive signal that includes a costimulatory domain of CD28, CD27, ICOS and GITR.

Exemplary GITR agonists include, e.g., GITR fusion proteins and anti-GITR antibodies (e.g., bivalent anti-GITR antibodies), such as, a GITR fusion protein described in U.S. Pat. No. 6,111,090, European Patent No.: 090505B1, U.S. Pat. No. 8,586,023, PCT Publication Nos.: WO 2010/003118 and 2011/090754, or an anti-GITR antibody described, e.g., in U.S. Pat. No. 7,025,962, European Patent No.: 1947183B1, U.S. Pat. Nos. 7,812,135, 8,388,967, 8,591,886, European Patent No.: EP 1866339, PCT Publication No.: WO 2011/028683, PCT Publication No.: WO 2013/039954, PCT Publication No.: WO2005/007190, PCT Publication No.: WO 2007/133822, PCT Publication No.: WO2005/055808, PCT Publication No.: WO 99/40196, PCT Publication No.: WO 2001/03720, PCT Publication No.: WO99/20758, PCT Publication No.: WO2006/083289, PCT Publication No.: WO 2005/115451, U.S. Pat. No. 7,618,632, and PCT Publication No.: WO 2011/051726.

In one embodiment, the anti-TIM-3 antibody molecule is administered in combination with an inhibitor of an immune checkpoint molecule (or immune inhibitory molecule). The term “immune checkpoints” as used herein refers to a group of molecules on the cell surface of immune cells, e.g., CD4 and CD8 T cells that can serve as “brakes” to down-modulate or inhibit an immune response, e.g., an anti-tumor immune response. Immune checkpoint molecules include, but are not limited to, Programmed Death 1 (PD-1), PD-L1, Cytotoxic T-Lymphocyte Antigen 4 (CTLA-4), B7-H1, B7-H3, B7-H4, OX-40, 4-1BB (CD137), CD40, T-cell immunoglobulin domain and mucin domain-3 (TIM-3), and Lymphocyte-activation gene 3 (LAG-3), among others. Immunotherapeutic agents that can act as inhibitors of immune checkpoint molecules useful in combination with the anti-PD-1 molecules described herein, include, but are not limited to, inhibitors of PD-L1, PD-L2, CTLA-4, TIM-3, LAG-3, VISTA, BTLA, TIGIT, LAIR1, CD160, 2B4, CEACAM (e.g., CEACAM-1, CEACM-3, and/or CEACAM-5), and/or TGFR beta. Inhibition of an immune inhibitory molecule can be performed by inhibition at the DNA, RNA or protein level. In embodiments, an inhibitory nucleic acid (e.g., a dsRNA, siRNA or shRNA), can be used to inhibit expression of an inhibitory molecule. In other embodiments, the inhibitor of an inhibitory signal is, a polypeptide e.g., a soluble ligand, or an antibody or antigen-binding fragment thereof, that binds to the inhibitory molecule.

In one embodiment, the inhibitor is a soluble ligand (e.g., a CTLA-4-Ig or a TIM-3-Ig), or an antibody or antibody fragment that binds to CTLA-4. For example, the anti-TIM-3 antibody molecule can be administered in combination with an anti-CTLA-4 antibody, e.g., ipilimumab, for example, to treat a cancer (e.g., a cancer chosen from: a melanoma, e.g., a metastatic melanoma; a lung cancer, e.g., a non-small cell lung carcinoma; or a prostate cancer). Exemplary anti-CTLA-4 antibodies include Tremelimumab (IgG2 monoclonal antibody available from Pfizer, formerly known as ticilimumab, CP-675,206); and Ipilimumab (CTLA-4 antibody, also known as MDX-010, CAS No. 477202-00-9). In one embodiment, the anti-TIM-3 antibody molecule is administered after treatment, e.g., after treatment of a melanoma, with an anti-CTLA-4 antibody (e.g., ipilimumab) with or without a BRAF inhibitor (e.g., vemurafenib or dabrafenib). Exemplary doses that can be use include a dose of anti-TIM-3 antibody molecule of about 1 to 30 mg/kg, 1 to 20 mg/kg, or 1 to 10 mg/kg, e.g., 3 mg/kg, and a dose of an anti-CTLA-4 antibody, e.g., ipilimumab, of about 3 mg/kg.

In certain embodiments, immune checkpoint molecules, e.g., PD-1, LAG-3, TIM-3, CEACAM-1/-5, can regulate T-cell function to promote tumoral immune escape. Thus, the anti-TIM-3 antibodies described herein can be used in combination with one or more inhibitors of these immune inhibitor molecules to enhance an anti-tumor response. The combination of antibodies recited herein can be administered separately, e.g., as separate antibodies, or linked, e.g., as a bispecific or trispecific antibody molecule.

In one embodiment, the anti-TIM-3 antibody molecule is administered in combination with an anti-TIM-3 antibody or an antigen-binding fragment thereof. In another embodiment, the anti-TIM-3 antibody molecule is administered in combination with an anti-PD-1 antibody or antigen-binding fragment thereof. In yet other embodiments, the anti-TIM-3 antibody molecule is administered in combination with an anti-TIM-3 antibody and an anti-PD-1 antibody, or antigen-binding fragments thereof. In one embodiment, a bispecific antibody that includes an anti-TIM-3 antibody molecule and an anti-PD-1 or anti-TIM-3 antibody, or antigen-binding fragment thereof, is administered. In certain embodiments, the combination of antibodies recited herein is used to treat a cancer, e.g., a cancer as described herein (e.g., a solid tumor). The efficacy of the aforesaid combinations can be tested in animal models known in the art. For example, the animal models to test the effect of anti-PD-1 and anti-LAG-3 are described, e.g., in Woo et al. (2012) Cancer Res. 72(4):917-27).

In some embodiments, the inhibitors of the TIM-3 and PD-1 molecules (e.g., anti-TIM-3 and anti-PD-1 antibody molecules) are administered in combination, e.g., to treat cancer. In some embodiments, the subject is a patient who has progressed (e.g., experienced tumor growth) during therapy with a PD-1 inhibitor (e.g., an antibody molecule as described herein) and/or a PD-L1 inhibitor (e.g., an anti-PD-L1 antibody molecule). In some embodiments, therapy with the PD-1 antibody molecule and/or PD-L1 antibody molecule is continued, and a TIM-3 immune inhibitory molecule (e.g., antibody) is added to the therapy.

In other embodiments, the anti-TIM-3 antibody molecule is administered in combination with a CEACAM inhibitor (e.g., CEACAM-1, CEACAM-3, and/or CEACAM-5 inhibitor). In one embodiment, the inhibitor of CEACAM is an anti-CEACAM antibody molecule. In one embodiment, the anti-TIM-3 antibody molecule is administered in combination with a CEACAM-1 inhibitor, e.g., an anti-CEACAM-1 antibody molecule. In another embodiment, the anti-TIM-3 antibody molecule is administered in combination with a CEACAM-3 inhibitor, e.g., an anti-CEACAM-3 antibody molecule. In another embodiment, the anti-TIM-3 antibody molecule is administered in combination with a CEACAM-5 inhibitor, e.g., an anti-CEACAM-5 antibody molecule. Exemplary anti-CEACAM-1 antibodies are described in WO 2010/125571, WO 2013/082366 and WO 2014/022332, e.g., a monoclonal antibody 34B1, 26H7, and 5F4; or a recombinant form thereof, as described in, e.g., US 2004/0047858, U.S. Pat. No. 7,132,255 and WO 99/052552. In other embodiments, the anti-CEACAM antibody binds to CEACAM-5 as described in, e.g., Zheng et al. PLoS One. 2010 Sep. 2; 5(9). pii: e12529 (DOI:10:1371/journal.pone.0021146), or crossreacts with CEACAM-1 and CEACAM-5 as described in, e.g., WO 2013/054331 and US 2014/0271618.

Without wishing to be bound by theory, carcinoembryonic antigen cell adhesion molecules (CEACAM), such as CEACAM-1 and CEACAM-5, are believed to mediate, at least in part, inhibition of an anti-tumor immune response (see e.g., Markel et al. J Immunol. 2002 Mar. 15; 168(6):2803-10; Markel et al. J Immunol. 2006 Nov. 1; 177(9):6062-71; Markel et al. Immunology. 2009 February; 126(2):186-200; Markel et al. Cancer Immunol Immunother. 2010 February; 59(2):215-30; Ortenberg et al. Mol Cancer Ther. 2012 June; 11(6):1300-10; Stern et al. J Immunol. 2005 Jun. 1; 174(11):6692-701; Zheng et al. PLoS One. 2010 Sep. 2; 5(9). pii: e12529). For example, CEACAM-1 has been described as a heterophilic ligand for TIM-3 and as playing a role in TIM-3-mediated T cell tolerance and exhaustion (see e.g., WO 2014/022332; Huang, et al. (2014) Nature doi:10.1038/nature13848). In embodiments, co-blockade of CEACAM-1 and TIM-3 has been shown to enhance an anti-tumor immune response in xenograft colorectal cancer models (see e.g., WO 2014/022332; Huang, et al. (2014), supra). In other embodiments, co-blockade of CEACAM-1 and PD-1 reduce T cell tolerance as described, e.g., in WO 2014/059251. Thus, CEACAM inhibitors can be used with the other immunomodulators described herein (e.g., anti-PD-1 and/or anti-TIM-3 inhibitors) to enhance an immune response against a cancer, e.g., a melanoma, a lung cancer (e.g., NSCLC), a bladder cancer, a colon cancer an ovarian cancer, and other cancers as described herein.

In some embodiments, the PD-1 and TIM-3 immune inhibitory molecules (e.g., antibody molecules) are administered in combination with each other, e.g., to treat cancer. In some embodiments, the patient is a patient who progressed (e.g., experienced tumor growth) during therapy with a PD-1 inhibitor (e.g., an antibody molecule as described herein) and/or a PDL1 inhibitor (e.g., antibody molecule). In some embodiments, therapy with the PD-1 antibody molecule and/or PDL1 antibody molecule is continued, and a TIM-3 immune inhibitory molecule (e.g., antibody) is added to the therapy.

In some embodiments, the TIM-3 and LAG-3 immune inhibitory molecules (e.g., antibody molecules) are administered in combination with each other, e.g., to treat cancer. In some embodiments, the patient is a patient who progressed (e.g., experienced tumor growth) during therapy with a TIM-3 inhibitor (e.g., an antibody molecule as described herein) and/or a PD-1 inhibitor (e.g., antibody molecule). In some embodiments, therapy with the anti-TIM-3 antibody molecule and/or PDL1 antibody molecule is continued, and a LAG-3 immune inhibitory molecule (e.g., antibody) is added to the therapy.

In other embodiments, the anti-TIM-3 antibody molecule is administered in combination with a cytokine, e.g., interleukin-21, interleukin-2, or interleukin 15. In certain embodiments, the combination of anti-TIM-3 antibody molecule and cytokine described herein is used to treat a cancer, e.g., a cancer as described herein (e.g., a solid tumor or melanoma).

Exemplary immunomodulators that can be used in combination with anti-TIM-3 antibody molecules include, but are not limited to, e.g., afutuzumab (available from Roche®); pegfilgrastim (Neulasta®); lenalidomide (CC-5013, Revlimid®); thalidomide (Thalomid®), actimid (CC4047); and cytokines, e.g., IL-21 or IRX-2 (mixture of human cytokines including interleukin 1, interleukin 2, and interferon γ, CAS 951209-71-5, available from IRX Therapeutics).

In yet other embodiments, the anti-TIM-3 antibody molecule is used in combination with an indoleamine-pyrrole 2,3-dioxygenase (IDO) inhibitor (e.g., INCB24360) in a subject with advanced or metastatic cancer (e.g., a patient with metastic and recurrent NSCL cancer).

In other embodiments, the anti-TIM-3 antibody molecules are administered to a subject in conjunction with (e.g., before, simultaneously or following) one or more of: bone marrow transplantation, T cell ablative therapy using chemotherapy agents such as, fludarabine, external-beam radiation therapy (XRT), cyclophosphamide, and/or antibodies such as OKT3 or CAMPATH. In one embodiment, the anti-TIM-3 antibody molecules are administered following B-cell ablative therapy such as agents that react with CD20, e.g., Rituxan. For example, in one embodiment, subjects may undergo standard treatment with high dose chemotherapy followed by peripheral blood stem cell transplantation. In certain embodiments, following the transplant, subjects receive the anti-TIM-3 antibody molecules. In an additional embodiment, the anti-TIM-3 antibody molecules are administered before or following surgery.

Another example of a combination is an anti-TIM-3 antibody in combination with decarbazine for the treatment of melanoma. Without being bound by theory, the combined use of TIM-3 blockade and chemotherapy is believed to be facilitated by cell death, that is a consequence of the cytotoxic action of most chemotherapeutic compounds, which can result in increased levels of tumor antigen in the antigen presentation pathway. Other combination therapies that may result in synergy with TIM-3 blockade through cell death are radiation, surgery, and hormone deprivation. Each of these protocols creates a source of tumor antigen in the host. Angiogenesis inhibitors may also be combined with TIM-3 blockade. Inhibition of angiogenesis leads to tumor cell death which may feed tumor antigen into host antigen presentation pathways.

TIM-3 blocking antibodies can also be used in combination with bispecific antibodies. Bispecific antibodies can be used to target two separate antigens. For example anti-Fc receptor/anti tumor antigen (e.g., Her-2/neu) bispecific antibodies have been used to target macrophages to sites of tumor. This targeting may more effectively activate tumor specific responses. The T cell arm of these responses would be augmented by the use of TIM-3 blockade. Alternatively, antigen may be delivered directly to DCs by the use of bispecific antibodies which bind to tumor antigen and a dendritic cell specific cell surface marker.

Tumors evade host immune surveillance by a large variety of mechanisms. Many of these mechanisms may be overcome by the inactivation of proteins which are expressed by the tumors and which are immunosuppressive. These include among others TGF-beta (Kehrl, J. et al. (1986) J. Exp. Med. 163: 1037-1050), IL-10 (Howard, M. & O'Garra, A. (1992) Immunology Today 13: 198-200), and Fas ligand (Hahne, M. et al. (1996) Science 274: 1363-1365). Antibodies or antigen-binding fragments thereof to each of these entities may be used in combination with anti-TIM-3 antibody molecules to counteract the effects of the immunosuppressive agent and favor tumor immune responses by the host.

Other antibodies which may be used to activate host immune responsiveness can be used in combination with anti-TIM-3 antibody molecules. These include molecules on the surface of dendritic cells which activate DC function and antigen presentation. Anti-CD40 antibodies are able to substitute effectively for T cell helper activity (Ridge, J. et al. (1998) Nature 393: 474-478) and can be used in conjunction with PD-1 antibodies (Ito, N. et al. (2000) Immunobiology 201 (5) 527-40). Antibodies to T cell costimulatory molecules such as CTLA-4 (e.g., U.S. Pat. No. 5,811,097), OX-40 (Weinberg, A. et al. (2000) Immunol 164: 2160-2169), 4-1BB (Melero, I. et al. (1997) Nature Medicine 3: 682-685 (1997), and ICOS (Hutloff, A. et al. (1999) Nature 397: 262-266) may also provide for increased levels of T cell activation.

Additional exemplary standard of care treatments are described in the section entitled “Combination Therapies” below.

In all of the methods described herein, TIM-3 blockade can be combined with other forms of immunotherapy such as cytokine treatment (e.g., interferons, GM-CSF, G-CSF, IL-2, IL-21), or bispecific antibody therapy, which provides for enhanced presentation of tumor antigens (see e.g., Holliger (1993) Proc. Natl. Acad. Sci. USA 90:6444-6448; Poljak (1994) Structure 2:1121-1123).

Methods of administering the antibody molecules are known in the art and are described below. Suitable dosages of the molecules used will depend on the age and weight of the subject and the particular drug used. Dosages and therapeutic regimens of the anti-TIM-3 antibody molecule can be determined by a skilled artisan. In certain embodiments, the anti-TIM-3 antibody molecule is administered by injection (e.g., subcutaneously or intravenously) at a dose of about 1 to 30 mg/kg, e.g., about 5 to 25 mg/kg, about 10 to 20 mg/kg, about 1 to 5 mg/kg, or about 3 mg/kg. In some embodiments, the anti-TIM-3 antibody molecule is administered at a dose of about 1 mg/kg, about 3 mg/kg, about 10 mg/kg, about 15 mg/kg, about 20 mg/kg, about 25 mg/kg or about 30 mg/kg. In some embodiments, the anti-TIM-3 antibody molecule is administered at a dose of about 1-3 mg/kg, about 3-10 mg/kg, about 3-15 mg/kg, about 10-15 mg/kg, about 10-20 mg/kg, about 10-25 mg/kg, or about 20-30 mg/kg. In some embodiments, the anti-TIM-3 antibody molecule is administered at a dose of about 0.5-2, 2-4, 2-5, or 5-15 mg/kg. The dosing schedule can vary from e.g., once a week to once every 2, 3, or 4 weeks. In one embodiment, the anti-TIM-3 antibody molecule is administered at a dose from about 10 to 20 mg/kg every other week.

The antibody molecules can be used by themselves or conjugated to a second agent, e.g., a cytotoxic drug, radioisotope, or a protein, e.g., a protein toxin or a viral protein. This method includes: administering the antibody molecule, alone or conjugated to a cytotoxic drug, to a subject requiring such treatment. The antibody molecules can be used to deliver a variety of therapeutic agents, e.g., a cytotoxic moiety, e.g., a therapeutic drug, a radioisotope, molecules of plant, fungal, or bacterial origin, or biological proteins (e.g., protein toxins) or particles (e.g., a recombinant viral particles, e.g.; via a viral coat protein), or mixtures thereof.

Anti-TIM-3 antibody molecules may also be combined with standard cancer treatments. For instance, anti-TIM-3 antibody molecules may be effectively combined with chemotherapeutic regimes. In these instances, it may be possible to reduce the dose of chemotherapeutic reagent administered (Mokyr, M. et al. (1998) Cancer Research 58: 5301-5304). An example of such a combination is an anti-TIM-3 antibody molecule in combination with decarbazine for the treatment of melanoma. Another example of such a combination is an anti-TIM-3 antibody molecule in combination with interleukin-2 (IL-2) for the treatment of melanoma. In some embodiments the anti-TIM-3 antibody molecule can be combined with IL-21. While not wishing to be bound by theory, one scientific rationale behind the combined use of anti-TIM-3 antibody molecule therapy and chemotherapy is that cell death, that is a consequence of the cytotoxic action of most chemotherapeutic compounds, should result in increased levels of tumor antigen in the antigen presentation pathway. Other combination therapies that may result in synergy with anti-TIM-3 antibody molecule therapy through cell death are radiation, surgery, and hormone deprivation. Each of these protocols creates a source of tumor antigen in the host. Angiogenesis inhibitors may also be combined with anti-TIM-3 antibody molecule therapy. Inhibition of angiogenesis leads to tumor cell death which may feed tumor antigen into host antigen presentation pathways. Anti-TIM-3 antibody molecules can also be used in combination with bispecific antibodies. Bispecific antibodies can be used to target two separate antigens. For example anti-Fc receptor/anti tumor antigen (e.g., Her-2/neu) bispecific antibodies have been used to target macrophages to sites of tumor. This targeting may more effectively activate tumor specific responses. The T cell arm of these responses would be augmented by the use of anti-TIM-3 antibody molecules. Alternatively, antigen may be delivered directly to DCs by the use of bispecific antibodies which bind to tumor antigen and a dendritic cell specific cell surface marker.

Tumors evade host immune surveillance by a large variety of mechanisms. Many of these mechanisms may be overcome by the inactivation of proteins which are expressed by the tumors and which are immunosuppressive. These include among others TGF-beta (Kehrl, J. et al. (1986) J. Exp. Med. 163: 1037-1050), IL-10 (Howard, M. & O'Garra, A. (1992) Immunology Today 13: 198-200), and Fas ligand (Hahne, M. et al. (1996) Science 274: 1363-1365). Antibodies to each of these entities may be used in combination with anti-TIM-3 antibody molecules to counteract the effects of the immunosuppressive agent and favor tumor immune responses by the host.

Other antibodies which may be used to activate host immune responsiveness can be used in combination with anti-TIM-3 antibody molecules. These include molecules on the surface of dendritic cells which activate DC function and antigen presentation. Anti-CD40 antibodies are able to substitute effectively for T cell helper activity (Ridge, J. et al. (1998) Nature 393: 474-478) and can be used in conjunction with anti-TIM-3 antibody molecules (see Ito, N. et al. (2000) Immunobiology 201 (5) 527-40).

This disclosure also provides a method of treating cancer with Compound A8, cetuximab, and a TIM-3 antibody molecule (optionally in combination with a PD-1 antibody molecule or LAG-3 antibody molecule). In some embodiments, the patient is first treated with Compound A8 and cetuximab. This treatment continues for an amount of time, e.g., a predetermined amount of time, e.g., about 1, 2, 4, 6, 8, 10, or 12 months. Next, the TIM-3 antibody molecule (optionally in combination with a PD-1 antibody molecule or LAG-3 antibody molecule) is administered. The TIM-3 antibody can optionally be administered in combination with cetuximab.

In some embodiments, the patient is first treated with all three of Compound A8, cetuximab, and a TIM-3 antibody molecule (optionally in combination with a PD-1 antibody molecule or LAG-3 antibody molecule). This treatment continues for an amount of time, e.g., a predetermined amount of time, e.g., about 6, 8, 10, or 12 months. Next, the Compound A8 and/or cetuximab can be tapered off, so that the maintenance phase involves treatment with the TIM-3 antibody molecule (e.g., as a monotherapy, or in combination with a PD-1 antibody molecule or LAG-3 antibody molecule) but not Compound A8 or cetuximab.

In other embodiments, the three compounds (Compound A8, cetuximab, and a TIM-3 antibody molecule, optionally in combination with a PD-1 antibody molecule or LAG-3 antibody molecule) are given sequentially at the outset of the treatment. For instance, Compound A8 and cetuximab can be given first, as described above. Next, the TIM-3 antibody molecule (optionally in combination with a PD-1 antibody molecule or LAG-3 antibody molecule) is added to the regimen. Next, the Compound A8 and/or cetuximab can be tapered off as described above.

Exemplary doses for the three (or more) agent regimens are as follows. The TIM-3 antibody molecule can be administered, e.g., at a dose of about 1 to 40 mg/kg, e.g., 1 to 30 mg/kg, e.g., about 5 to 25 mg/kg, about 10 to 20 mg/kg, about 1 to 5 mg/kg, or about 3 mg/kg. In some embodiments, the Compound A8 is administered at a dose of approximately 200-300, 300-400, or 200-400 mg. In some embodiments, the cetuximab is administered at a 400 mg/m2 initial dose as a 120-minute intravenous infusion followed by 250 mg/m2 weekly infused over 60 minutes. In embodiments, one or more of the Compound A8, cetuximab, and TIM-3 antibody molecule is administered at a dose that is lower than the dose at which that agent is typically administered as a monotherapy, e.g., about 0-10%, 10-20%, 20-30%, 30-40%, 40-50%, 50-60%, 60-70%, 70-80%, or 80-90% lower than the dose at which that agent is typically administered as a monotherapy. In embodiments, the one or more of the Compound A8, cetuximab, and TIM-3 antibody molecule is administered at a dose that is lower than the dose of that agent recited in this paragraph, e.g., about 0-10%, 10-20%, 20-30%, 30-40%, 40-50%, 50-60%, 60-70%, 70-80%, or 80-90% lower than the dose of that agent recited in this paragraph. In certain embodiments, the concentration of the Compound A8 that is required to achieve inhibition, e.g., growth inhibition, is lower when the Compound A8 is administered in combination with one or both of the cetuximab and TIM-3 antibody molecule than when the Compound A8 is administered individually. In certain embodiments, the concentration of the cetuximab that is required to achieve inhibition, e.g., growth inhibition, is lower when the cetuximab is administered in combination with one or both of the Compound A8 and TIM-3 antibody molecule than when the cetuximab is administered individually. In certain embodiments, the concentration of the TIM-3 antibody molecule that is required to achieve inhibition, e.g., growth inhibition, is lower when the TIM-3 antibody molecule is administered in combination with one or both of the cetuximab and Compound A8 than when the TIM-3 antibody molecule is administered individually.

Additionally disclosed herein is a method of treating cancer with the anti-TIM-3 antibody molecules, alone or in combination with another immunomodulator (e.g., an anti-LAG-3, anti-PD-L1 or anti-PD-1 antibody molecule), and a targeted anti-cancer agent, e.g., an agent that targets one or more proteins. In some embodiments, the anti-TIM-3 antibody molecule (and optionally other immunomodulator(s)) are administered first, and the targeted anti-cancer agent is administered second. The length of time between administration of the anti-TIM-3 antibody molecule and the targeted anti-cancer agent can be, e.g., 10, 20, or 30 minutes, 1, 2, 4, 6, or 12 hours, or 1, 2, 3, 4, 5, 6, or 7 days, or any span of time within this range. In certain embodiments, the anti-TIM-3 antibody molecule is administered repeatedly over a period of time (e.g., 1, 2, 3, 4, 5, or 6 days, or 1, 2, 4, 8, 12, 16, or 20 weeks, or any span of time within this range) before the targeted anti-cancer agent is administered. In other embodiments, the anti-TIM-3 antibody molecule and the targeted anti-cancer agent are administered at substantially the same time.

Methods of Treating Infectious Diseases

Other methods of the invention are used to treat patients that have been exposed to particular toxins or pathogens. Based on, at least, the Examples herein, anti-TIM-3 antibodies can stimulate NK cell mediated killing of target cells and can enhances IFN-gamma secretion and proliferation of CD4+ T cells. Accordingly, in certain embodiments, the anti-TIM-3 antibody molecules described herein are suitable for use in stimulating an immune response against an infectious agent. Accordingly, another aspect of the invention provides a method of treating an infectious disease in a subject comprising administering to the subject an anti-TIM-3 antibody molecule, such that the subject is treated for the infectious disease. In the treatment of infection (e.g., acute and/or chronic), administration of the anti-TIM-3 antibody molecules can be combined with conventional treatments in addition to or in lieu of stimulating natural host immune defenses to infection. Natural host immune defenses to infection include, but are not limited to inflammation, fever, antibody-mediated host defense, T-lymphocyte-mediated host defenses, including lymphokine secretion and cytotoxic T-cells (especially during viral infection), complement mediated lysis and opsonization (facilitated phagocytosis), and phagocytosis. The ability of the anti-TIM-3 antibody molecules to reactivate dysfunctional T-cells would be useful to treat chronic infections, in particular those in which cell-mediated immunity is important for complete recovery.

Certain methods described herein are used to treat patients that have been exposed to particular toxins or pathogens. Some aspects provides a method of treating an infectious disease in a subject comprising administering to the subject an anti-TIM-3 antibody molecule, such that the subject is treated for the infectious disease.

Similar to its application to tumors as discussed in the previous section, aIn embodiments, the anti-TIM-3 antibody molecules can be used alone, or as an adjuvant, in combination with vaccines, to stimulate the immune response to, e.g., pathogens or toxins. Examples of pathogens for which this therapeutic approach may be particularly useful, include pathogens for which there is currently no effective vaccine, or pathogens for which conventional vaccines are less than completely effective. These include, but are not limited to HIV, Hepatitis (A, B, & C), Influenza, Herpes, Giardia, Malaria, Leishmania, Staphylococcus aureus, Pseudomonas Aeruginosa. Anti-TIM-3 antibody molecule therapy is also useful against established infections by agents such as HIV that present altered antigens over the course of the infections.

Accordingly, in some embodiments an anti-TIM-3 antibody molecule is used to treat a subject that has an infection or is at risk of having an infection. An infection refers to, e.g., a disease or condition attributable to the presence in a host of a foreign organism or agent that reproduces within the host. Infections typically involve breach of a normal mucosal or other tissue barrier by an infectious organism or agent. A subject that has an infection is a subject having objectively measurable infectious organisms or agents present in the subject's body. A subject at risk of having an infection is a subject that is predisposed to develop an infection. Such a subject can include, for example, a subject with a known or suspected exposure to an infectious organism or agent. A subject at risk of having an infection also can include a subject with a condition associated with impaired ability to mount an immune response to an infectious organism or agent, e.g., a subject with a congenital or acquired immunodeficiency, a subject undergoing radiation therapy or chemotherapy, a subject with a burn injury, a subject with a traumatic injury, a subject undergoing surgery or other invasive medical or dental procedure.

Infections are broadly classified as bacterial, viral, fungal, or parasitic based on the category of infectious organism or agent involved. Other less common types of infection include, e.g., infections involving rickettsiae, mycoplasmas, and agents causing scrapie, bovine spongiform encephalopthy (BSE), and prion diseases (e.g., kuru and Creutzfeldt-Jacob disease). Examples of bacteria, viruses, fungi, and parasites which cause infection are well known in the art. An infection can be acute, subacute, chronic, or latent, and it can be localized or systemic. Furthermore, an infection can be predominantly intracellular or extracellular during at least one phase of the infectious organism's or agent's life cycle in the host.

Examples of viruses that have been found to cause infections in humans include but are not limited to: Retroviridae (e.g., human immunodeficiency viruses, such as HIV-1 (also referred to as HTLV-III), HIV-2, LAV or HTLV-III/LAV, or HIV-III, and other isolates, such as HIV-LP; Picornaviridae (e.g., polio viruses, hepatitis A virus; enteroviruses, human Coxsackie viruses, rhinoviruses, echoviruses); Calciviridae (e.g., strains that cause gastroenteritis); Togaviridae (e.g., equine encephalitis viruses, rubella viruses); Flaviviridae (e.g., dengue viruses, encephalitis viruses, yellow fever viruses); Coronaviridae (e.g., coronaviruses); Rhabdoviridae (e.g., vesicular stomatitis viruses, rabies viruses); Filoviridae (e.g., ebola viruses); Paramyxoviridae (e.g., parainfluenza viruses, mumps virus, measles virus, respiratory syncytial virus); Orthomyxoviridae (e.g., influenza viruses); Bungaviridae (e.g., Hantaan viruses, bunga viruses, phleboviruses and Nairo viruses); Arena viridae (hemorrhagic fever viruses); Reoviridae (e.g., reoviruses, orbiviurses and rotaviruses); Birnaviridae; Hepadnaviridae (Hepatitis B virus); Parvoviridae (parvoviruses); Papovaviridae (papilloma viruses, polyoma viruses); Adenoviridae (most adenoviruses); Herpesviridae (herpes simplex virus (HSV) 1 and 2, varicella zoster virus, cytomegalovirus (CMV), herpes virus; Poxyiridae (variola viruses, vaccinia viruses, pox viruses); and Iridoviridae (e.g., African swine fever virus); and unclassified viruses (e.g., the etiological agents of Spongiform encephalopathies, the agent of delta hepatitis (thought to be a defective satellite of hepatitis B virus), the agents of non-A, non-B hepatitis (class 1=enterally transmitted; class 2=parenterally transmitted (i.e., Hepatitis C); Norwalk and related viruses, and astroviruses). Some examples of pathogenic viruses causing infections treatable by methods herein include HIV, hepatitis (A, B, or C), herpes virus (e.g., VZV, HSV-1, HAV-6, HSV-II, and CMV, Epstein Barr virus), adenovirus, influenza virus, flaviviruses, echovirus, rhinovirus, coxsackie virus, cornovirus, respiratory syncytial virus, mumps virus, rotavirus, measles virus, rubella virus, parvovirus, vaccinia virus, HTLV virus, dengue virus, papillomavirus, molluscum virus, poliovirus, rabies virus, JC virus and arboviral encephalitis virus.

For infections resulting from viral causes, the anti-TIM-3 antibody molecules can be combined by application simultaneous with, prior to or subsequent to application of standard therapies for treating viral infections. Such standard therapies vary depending upon type of virus, although in almost all cases, administration of human serum containing antibodies (e.g., IgA, IgG) specific to the virus can be effective.

Some examples of pathogenic viruses causing infections treatable by methods include HIV, hepatitis (A, B, or C), herpes virus (e.g., VZV, HSV-1, HAV-6, HSV-II, and CMV, Epstein Barr virus), adenovirus, influenza virus, flaviviruses, echovirus, rhinovirus, coxsackie virus, cornovirus, respiratory syncytial virus, mumps virus, rotavirus, measles virus, rubella virus, parvovirus, vaccinia virus, HTLV virus, dengue virus, papillomavirus, molluscum virus, poliovirus, rabies virus, JC virus, arboviral encephalitis virus, and ebolaviruses (e.g., BDBV, EBOV, RESTV, SUDV and TAFV).

In one embodiment, the infection is an influenza infection. Influenza infection can result in fever, cough, myalgia, headache and malaise, which often occur in seasonal epidemics. Influenza is also associated with a number of postinfectious disorders, such as encephalitis, myopericarditis, Goodpasture's syndrome, and Reye's syndrome. Influenza infection also suppresses normal pulmonary antibacterial defenses, such that patient's recovering from influenza have an increased risk of developing bacterial pneumonia. Influenza viral surface proteins show marked antigenic variation, resulting from mutation and recombination. Thus, cytolytic T lymphocytes are the host's primary vehicle for the elimination of virus after infection. Influenza is classified into three primary types: A, B and C. Influenza A is unique in that it infects both humans and many other animals (e.g., pigs, horses, birds and seals) and is the principal cause of pandemic influenza. Also, when a cell is infected by two different influenza A strains, the segmented RNA genomes of two parental virus types mix during replication to create a hybrid replicant, resulting in new epidemic strains. Influenza B does not replicate in animals and thus has less genetic variation and influenza C has only a single serotype.

Most conventional therapies are palliatives of the symptoms resulting from infection, while the host's immune response actually clears the disease. However, certain strains (e.g., influenza A) can cause more serious illness and death. Influenza A may be treated both clinically and prophylactically by the administration of the cyclic amines inhibitors amantadine and rimantadine, which inhibit viral replication. However, the clinical utility of these drugs is limited due to the relatively high incidence of adverse reactions, their narrow anti-viral spectrum (influenza A only), and the propensity of the virus to become resistant. The administration of serum IgG antibody to the major influenza surface proteins, hemagglutinin and neuraminidase can prevent pulmonary infection, whereas mucosal IgA is required to prevent infection of the upper respiratory tract and trachea. The most effective current treatment for influenza is vaccination with the administration of virus inactivated with formalin or β-propiolactone.

In another embodiment, the infection is a hepatitis infection, e.g., a Hepatitis B or C infection.

Hepatitis B virus (HB-V) is the most infectious known bloodborne pathogen. It is a major cause of acute and chronic heptatis and hepatic carcinoma, as well as life-long, chronic infection. Following infection, the virus replicates in hepatocytes, which also then shed the surface antigen HBsAg. The detection of excessive levels of HBsAg in serum is used a standard method for diagnosing a hepatitis B infection. An acute infection may resolve or it can develop into a chronic persistent infection. Current treatments for chronic HBV include α-interferon, which increases the expression of class I human leukocyte antigen (HLA) on the surface of hepatocytes, thereby facilitating their recognition by cytotoxic T lymphocytes. Additionally, the nucleoside analogs ganciclovir, famciclovir and lamivudine have also shown some efficacy in the treatment of HBV infection in clinical trials. Additional treatments for HBV include pegylated a-interferon, adenfovir, entecavir and telbivudine. While passive immunity can be conferred through parental administration of anti-HBsAg serum antibodies, vaccination with inactivated or recombinant HBsAg also confers resistance to infection. The anti-TIM-3 antibody molecules may be combined with conventional treatments for hepatitis B infections for therapeutic advantage.

Hepatitis C virus (HC-V) infection may lead to a chronic form of hepatitis, resulting in cirrosis. While symptoms are similar to infections resulting from Hepatitis B, in distinct contrast to HB-V, infected hosts can be asymptomatic for 10-20 years. The anti-TIM-3 antibody molecule can be administered as a monotherapy, or combined with the standard of care for hepatitis C infection. For example, the anti-TIM-3 antibody molecule can be administered with one or more of Sovaldi (sofosbuvir) Olysio (simeprevir), plus ribavirin or pegylated interferon. Although regimens that include Incivek (telaprevir) or Victrelis (boceprevir) plus ribavirin and pegylated interferon are also approved, they are associated with increased side effects and longer duration of treatment and are therefore not considered preferred regimens.

Conventional treatment for HC-V infection includes the administration of a combination of α-interferon and ribavirin. A promising potential therapy for HC-V infection is the protease inhibitor telaprevir (VX-960). Additional treatments include: anti-PD-1 antibody (MDX-1106, Medarex), bavituximab (an antibody that binds anionic phospholipid phosphatidylserine in a B2-glycoprotein I dependent manner, Peregrine Pharmaceuticals), anti-HPV viral coat protein E2 antibod(y)(ies) (e.g., ATL 6865-Ab68+Ab65, XTL Pharmaceuticals) and Civacir® (polyclonal anti-HCV human immune globulin). The anti-PD-L1 antibodies of the invention may be combined with one or more of these treatments for hepatitis C infections for therapeutic advantage. Protease, polymerase and NS5A inhibitors which may be used in combination with the anti-TIM-3 antibody molecules to specifically treat Hepatitis C infection include those described in US 2013/0045202, incorporated herein by reference.

In another embodiment, the infection is a measles virus. After an incubation of 9-11 days, hosts infected with the measles virus develop fever, cough, coryza and conjunctivitis. Within 1-2 days, an erythematous, maculopapular rash develop, which quickly spreads over the entire body. Because infection also suppresses cellular immunity, the host is at greater risk for developing bacterial superinfections, including otitis media, pneumonia and postinfectious encephalomyelitis. Acute infection is associated with significant morbidity and mortality, especially in malnourished adolescents.

Treatment for measles includes the passive administration of pooled human IgG, which can prevent infection in non-immune subjects, even if given up to one week after exposure. However, prior immunization with live, attenuated virus is the most effective treatment and prevents disease in more than 95% of those immunized. As there is one serotype of this virus, a single immunization or infection typically results in protection for life from subsequent infection.

In a small proportion of infected hosts, measles can develop into SSPE, which is a chronic progressive neurologic disorder resulting from a persistent infection of the central nervous system. SSPE is caused by clonal variants of measles virus with defects that interfere with virion assembly and budding. For these patients, reactivation of T-cells with the anti-TIM-3 antibody molecules so as to facilitate viral clearance would be desirable.

In another embodiment, the infection is HIV. HIV attacks CD4⁺ cells, including T-lymphocytes, monocyte-macrophages, follicular dendritic cells and Langerhan's cells, and CD4⁺ helper/inducer cells are depleted. As a result, the host acquires a severe defect in cell-mediated immunity. Infection with HIV results in AIDS in at least 50% of individuals, and is transmitted via sexual contact, administration of infected blood or blood products, artificial insemination with infected semen, exposure to blood-containing needles or syringes and transmission from an infected mother to infant during childbirth.

A host infected with HIV may be asymptomatic, or may develop an acute illness that resembling mononucleosis—fever, headache, sore throat, malaise and rash. Symptoms can progress to progressive immune dysfunction, including persistent fever, night sweats, weight loss, unexplained diarrhea, eczema, psoriasis, seborrheic dermatitis, herpes zoster, oral candidiasis and oral hairy leukoplakia. Opportunistic infections by a host of parasites are common in patients whose infections develop into AIDS.

Treatments for HIV include antiviral therapies including nucleoside analogs, zidovudine (AST) either alone or in combination with didanosine or zalcitabine, dideoxyinosine, dideoxycytidine, lamidvudine, stavudine; reverse transcriptive inhibitors such as delavirdine, nevirapine, loviride, and proteinase inhibitors such as saquinavir, ritonavir, indinavir and nelfinavir. The anti-TIM-3 antibody molecules may be combined with conventional treatments for HIV infections for therapeutic advantage.

In another embodiment, the infection is a Cytomegalovirus (CMV). CMV infection is often associated with persistent, latent and recurrent infection. CMV infects and remains latent in monocytes and granulocyte-monocyte progenitor cells. The clinical symptoms of CMV include mononucleosis-like symptoms (i.e., fever, swollen glands, malaise), and a tendancy to develop allergic skin rashes to antibiotics. The virus is spread by direct contact. The virus is shed in the urine, saliva, semen and to a lesser extent in other body fluids. Transmission can also occur from an infected mother to her fetus or newborn and by blood transfusion and organ transplants. CMV infection results in general impairment of cellular immunity, characterized by impaired blastogenic responses to nonspecific mitogens and specific CMV antigens, diminished cytotoxic ability and elevation of CD8 lymphocyte number of CD4⁺ lymphocytes.

Treatments of CMV infection include the anti-virals ganciclovir, foscarnet and cidovir, but these druges are typically only prescribed in immunocompromised patients. The anti-TIM-3 antibody molecules may be combined with conventional treatments for cytomegalovirus infections for therapeutic advantage.

In another embodiment, the infection is Epstein-Barr virus (EBV). EBV can establish persistent and latent infections and primarily attacks B cells. Infection with EBV results in the clinical condition of infectious mononucleosis, which includes fever, sore throat, often with exudate, generalized lymphadenopathy and splenomegaly. Hepatitis is also present, which can develop into jaundice.

While typical treatments for EBV infections are palliative of symptoms, EBV is associated with the development of certain cancers such as Burkitt's lymphoma and nasopharyngeal cancer. Thus, clearance of viral infection before these complications result would be of great benefit. The anti-TIM-3 antibody molecules may be combined with conventional treatments for Epstein-Barr virus infections for therapeutic advantage.

In another embodiment, the infection is Herpes simplex virus (HSV). HSV is transmitted by direct contact with an infected host. A direct infection may be asymptomatic, but typically result in blisters containing infectious particles. The disease manifests as cycles of active periods of disease, in which lesions appear and disappear as the viral latently infect the nerve ganglion for subsequent outbreaks. Lesions may be on the face, genitals, eyes and/or hands. In some case, an infection can also cause encephalitis.

Treatments for herpes infections are directed primarily to resolving the symptomatic outbreaks, and include systemic antiviral medicines such as: acyclovir (e.g., Zovirax®), valaciclovir, famciclovir, penciclovir, and topical medications such as docosanol (Abreva®), tromantadine and zilactin. The clearance of latent infections of herpes would be of great clinical benefit. The anti-TIM-3 antibody molecules may be combined with conventional treatments for herpes virus infections for therapeutic advantage.

In another embodiment, the infection is Human T-lymphotrophic virus (HTLV-1, HTLV-2). HTLV is transmitted via sexual contact, breast feeding or exposure to contaminated blood. The virus activates a subset of TH cells called Th1 cells, resulting in their overproliferation and overproduction of Th1 related cytokines (e.g., IFN-γ and TNF-α). This in turn results in a suppression of Th2 lymphocytes and reduction of Th2 cytokine production (e.g., IL-4, IL-5, IL-10 and IL-13), causing a reduction in the ability of an infected host to mount an adequate immune response to invading organisms requiring a Th2-dependent response for clearance (e.g., parasitic infections, production of mucosal and humoral antibodies).

HTLV infections cause lead to opportunistic infections resulting in bronchiectasis, dermatitis and superinfections with Staphylococcus spp. and Strongyloides spp. resulting in death from polymicrobial sepsis. HTLV infection can also lead directly to adult T-cell leukemia/lymphoma and progressive demyelinating upper motor neuron disease known as HAM/TSP. The clearance of HTLV latent infections would be of great clinical benefit. The anti-TIM-3 antibody molecules may be combined with conventional treatments for HTLV infections for therapeutic advantage.

In another embodiment, the infection is Human papilloma virus (HPV). HPV primarily affects keratinocytes and occurs in two forms: cutaneous and genital. Transmission is believed to occur through direct contact and/or sexual activity. Both cutaneous and genital HPV infection, can result in warts and latent infections and sometimes recurring infections, which are controlled by host immunity which controls the symptoms and blocks the appearance of warts, but leaves the host capable of transmitting the infection to others.

Infection with HPV can also lead to certain cancers, such as cervical, anal, vulvar, penile and oropharynial cancer. There are no known cures for HPV infection, but current treatment is topical application of Imiquimod, which stimulates the immune system to attack the affected area. The clearance of HPV latent infections would be of great clinical benefit. The anti-TIM-3 antibodies of the invention may be combined with conventional treatments for HPV infections for therapeutic advantage.

In another embodiment, the infection is Ebola virus (EBOV). EBOV is one of five known viruses within the Ebolavirus genus. EBOV causes severe and often fatal hemorrhagic fever in humans and mammals, known as Ebola virus disease (EVD). Transmission occurs through contact with blood, secretions, organs, or other boldily fluids of infected patients. Currently, there is no proven treatment or vaccine.

The anti-TIM-3 antibody molecules can be used in combination with existing treatment modalities for the aforesaid infections. For example, Treatments for syphilis include penicillin (e.g., penicillin G.), tetracycline, doxycycline, ceftriaxone and azithromycin.

Lyme disease, caused by Borrelia burgdorferi is transmitted into humans through tick bites. The disease manifests initially as a localized rash, followed by flu-like symptoms including malaise, fever, headache, stiff neck and arthralgias. Later manifestations can include migratory and polyarticular arthritis, neurologic and cardiac involvement with cranial nerve palsies and radiculopathy, myocarditis and arrhythmias. Some cases of Lyme disease become persistent, resulting in irreversible damage analogous to tertiary syphilis. Current therapy for Lyme disease includes primarily the administration of antibiotics. Antibiotic-resistant strains may be treated with hydroxychloroquine or methotrexate. Antibiotic refractory patients with neuropathic pain can be treated with gabapentin. Minocycline may be helpful in late/chronic Lyme disease with neurological or other inflammatory manifestations.

Other forms of borreliois, such as those resulting from B. recurentis, B. hermsii, B. turicatae, B. parikeri, B. hispanica, B. duttonii and B. persica, as well leptospirosis (E.g., L. interrogans), typically resolve spontaneously unless blood titers reach concentrations to cause intrahepatic obstruction.

In some embodiments, the infectious disease is chosen from hepatitis (e.g., hepatis C infection), or sepsis.

In all of the above methods, anti-TIM-3 antibody molecule therapy can be combined with other forms of immunotherapy such as cytokine treatment (e.g., interferons, GM-CSF, G-CSF, IL-2, IL-21), or bispecific antibody therapy, which provides for enhanced presentation of tumor antigens (see, e.g., Holliger (1993) Proc. Natl. Acad. Sci. USA 90:6444-6448; Poljak (1994) Structure 2:1121-1123).

Methods of administering various antibody molecules are known in the art and are described below. Suitable dosages of the antibody molecules used will depend on the age and weight of the subject and the particular drug used. The antibody molecules can be used as competitive agents for ligand binding to inhibit or reduce an undesirable interaction.

The antibody molecules can be used by themselves or conjugated to a second agent, e.g., a cytotoxic drug, radioisotope, or a protein, e.g., a protein toxin or a viral protein. This method includes: administering the antibody molecule, alone or conjugated to a cytotoxic drug, to a subject requiring such treatment. The antibody molecules can be used to deliver a variety of therapeutic agents, e.g., a cytotoxic moiety, e.g., a therapeutic drug, a radioisotope, molecules of plant, fungal, or bacterial origin, or biological proteins (e.g., protein toxins) or particles (e.g., a recombinant viral particles, e.g.; via a viral coat protein), or mixtures thereof.

Additional Combination Therapies

The anti-TIM-3 antibody molecules can be used in combination with other therapies. For example, the combination therapy can include an anti-TIM-3 antibody molecule co-formulated with, and/or co-administered with, one or more additional therapeutic agents, e.g., one or more anti-cancer agents, cytotoxic or cytostatic agents, hormone treatment, vaccines, and/or other immunotherapies. In other embodiments, the antibody molecules are administered in combination with other therapeutic treatment modalities, including surgery, radiation, cryosurgery, and/or thermotherapy. Such combination therapies may advantageously utilize lower dosages of the administered therapeutic agents, thus avoiding possible toxicities or complications associated with the various monotherapies.

Administered “in combination”, as used herein, means that two (or more) different treatments are delivered to the subject during the course of the subject's affliction with the disorder, e.g., the two or more treatments are delivered after the subject has been diagnosed with the disorder and before the disorder has been cured or eliminated. In some embodiments, the delivery of one treatment is still occurring when the delivery of the second begins, so that there is overlap. This is sometimes referred to herein as “simultaneous” or “concurrent delivery.” In other embodiments, the delivery of one treatment ends before the delivery of the other treatment begins. In some embodiments of either case, the treatment is more effective because of combined administration. For example, the second treatment is more effective, e.g., an equivalent effect is seen with less of the second treatment, or the second treatment reduces symptoms to a greater extent, than would be seen if the second treatment were administered in the absence of the first treatment, or the analogous situation is seen with the first treatment. In some embodiments, delivery is such that the reduction in a symptom, or other parameter related to the disorder is greater than what would be observed with one treatment delivered in the absence of the other. The effect of the two treatments can be partially additive, wholly additive, or greater than additive. The delivery can be such that an effect of the first treatment delivered is still detectable when the second is delivered.

Anti-TIM-3 antibody molecules can be administered in combination with one or more of the existing modalities for treating cancers, including, but not limited to: surgery; radiation therapy (e.g., external-beam therapy which involves three dimensional, conformal radiation therapy where the field of radiation is designed.

Exemplary huMLR assay and B or T cell proliferation assays are provided below.

Human Mixed Lymphocyte Reaction

The Mixed Lymphocyte Reaction (MLR) is a functional assay which measures the proliferative response of lymphocytes from one individual (the responder) to lymphocytes from another individual (the stimulator). To perform an allogeneic MLR, peripheral blood mononuclear cells (PBMC) from three donors were isolated from buffy-coats of unknown HLA type (Kantonspital Blutspendezentrum from Bern and Aarau, Switzerland). The cells were prepared at 2.105 in 0.2 mL of culture medium containing RPMI 1640 GlutaMAX™ with 10% fetal calf serum (FCS), 100 U penicillin/100 μg streptomycin, 50 μM 2-Mercaptoethanol. Individual 2-way reactions were set up by mixing PBMC from two different donors at a 1:1 ratio and co-cultures were done in triplicates in flat-bottomed 96-well tissue culture plates for 6 days at 37° C., 5% CO2, in presence or not of an 8-point concentration range of test compounds. Cells were pulsed with 3H-TdR (1 μCi/0.2 mL) for the last 16 h of culture and incorporated radioactivity was used as a measure of cell proliferation. The concentration that inhibited 50% of the maximal huMLR response (IC50) was calculated for each compound. Cyclosporine was used as a positive control of huMLR inhibition.

Human B Cell Proliferation Assay

PBMC were freshly isolated by Ficoll-Paque density gradient from human blood and subjected to negative B-cell isolation. B cells were resuspended in culture medium (RPMI 1640, HEPES, 10% FCS, 50 μg/mL gentamicine, 50 μM 2-Mercaptoethanol, 1×ITS (Insulin, Transferrin and Sodium Selenite), 1× Non-Essential Amino-Acids) at a concentration of 9.104 per well in a flat-bottom 96-well culture plate. B cell stimulation was performed by human anti-IgM antibody molecule (30 ug/mL) and IL-4 (75 ng/mL) or by CD40 ligand (3 ug/mL) and IL-4 (75 ng/mL) in presence or not of a 7-point concentration range of test compounds. After 72 h of culture at 37° C., 10% CO2, cells were pulsed with 3H-TdR (1 μCi/well) for the last 6 h of culture. B cells were then harvested and the incorporation of thymidine was measured using a scintillation counter. Of each duplicate treatment, the mean was calculated and these data were plotted in XLfit 4 to determine the respective IC50 values.

Human T Cell Proliferation Assay

PBMC were freshly isolated by Ficoll-Paque density gradient from human blood and subjected to negative isolation of T cells. T cells were prepared in culture medium (RPMI 1640, HEPES, 10% FCS, 50 μg/mL gentamicine, 50 μM 2-Mercaptoethanol, lx ITS (Insulin, Transferrin and Sodium Selenite), lx Non-Essential Amino-Acids) at a concentration of 8.104 per well in a flat-bottom 96-well culture plate. T cell stimulation was performed by human anti-CD3 antibody molecule (10 ug/mL) or by human anti-CD3 antibody molecule (5 μg/mL) and anti-CD28 antibody molecule (1 μg/mL) in presence or not of a 7-point concentration range of test compounds. After 72 h of culture at 37° C., 10% CO2, cells were pulsed with 3H-TdR (1 μCi/well) for the last 6 h of culture. Cell proliferation was measured by the incorporation of thymidine allowing IC50 determination for each tested compound.

Down-Modulators of the Immune System

In an alternative embodiment, the anti-TIM-3 antibody molecules disclosed herein are used to produce anti-idiotypic peptides or antibodies (Wallmann, J. et al. (2010) “Anti-Ids in Allergy: Timeliness of a Classic Concept,” World Allergy Organiz. J. 3(6):195-201; Nardi, M. et al. (2000) “Antiidiotype Antibody Against Platelet Anti-Gpiiia Contributes To The Regulation Of Thrombocytopenia In HIV-1-ITP Patients,” J. Exp. Med. 191(12):2093-2100) or mimetics (Zang, Y. C. et al. (2003) “Human Anti-Idiotypic T Cells Induced By TCR Peptides Corresponding To A Common CDR3 Sequence Motif In Myelin Basic Protein-Reactive T Cells,” Int. Immunol. 15(9):1073-1080; Loiarro, M. et al. (Epub 2010 Apr. 8) “Targeting TLR/IL-1R Signalling In Human Diseases,” Mediators Inflamm. 2010:674363) of TIM-3. Such molecules serve as surrogates for TIM-3, and thus their administration to a subject down-modulates the immune system of such subject by mimicking or facilitating ligand-TIM-3 binding. Such molecules have utility in the treatment of graft vs. host disease. Similarly, agonist antibodies that i) enhance binding between such antibodies and such receptor/ligand or ii) trigger signal transduction when bound directly to a TIM-3 ligand or TIM-3, have utility as agonists of TIM-3 signaling and thus have utility in the treatment of inflammation and autoimmune disease, by directly or indirectly agonizing receptor activity.

Bispecific antibodies, exhibiting immunospecific binding to both TIM-3 and TIM-3 ligands are capable of binding to both APC and T-cells, and thus facilitate the co-localization of APCs and T-cells. Such co-localization facilitates the ability of such cells to bind together via TIM-3 ligand and TIM-3 molecules that are not complexed with antibody, or by co-inhibitory molecules. Such binding provides down modulation of the immune system of the recipient.

Down-modulation of the immune system is desirable in the treatment of inflammatory and auto-immune diseases, and graft vs. host disease (GvHD). Examples of autoimmune disorders that may be treated by administering the antibodies of the present invention include, but are not limited to, alopecia greata, ankylosing spondylitis, antiphospholipid syndrome, autoimmune Addison's disease, autoimmune diseases of the adrenal gland, autoimmune hemolytic anemia, autoimmune hepatitis, autoimmune oophoritis and orchitis, autoimmune thrombocytopenia, Behcet's disease, bullous pemphigoid, cardiomyopathy, celiac sprue-dermatitis, chronic fatigue immune dysfunction syndrome (CFIDS), chronic inflammatory demyelinating polyneuropathy, Churg-Strauss syndrome, cicatrical pemphigoid, CREST syndrome, cold agglutinin disease, Crohn's disease, discoid lupus, essential mixed cryoglobulinemia, fibromyalgia-fibromyositis, glomerulonephritis, Graves' disease, Guillain-Barre, Hashimoto's thyroiditis, idiopathic pulmonary fibrosis, idiopathic thrombocytopenia purpura (ITP), IgA neuropathy, juvenile arthritis, lichen planus, lupus erthematosus, Meniere's disease, mixed connective tissue disease, multiple sclerosis, Neuromyelitis optica (NMO), type 1 or immune-mediated diabetes mellitus, myasthenia gravis, pemphigus vulgaris, pernicious anemia, polyarteritis nodosa, polychrondritis, polyglandular syndromes, polymyalgia rheumatica, polymyositis and dermatomyositis, primary agammaglobulinemia, primary biliary cirrhosis, psoriasis, psoriatic arthritis, Raynauld's phenomenon, Reiter's syndrome, Rheumatoid arthritis, sarcoidosis, scleroderma, Sjogren's syndrome, stiff-man syndrome, systemic lupus erythematosus, lupus erythematosus, takayasu arteritis, temporal arteristis/giant cell arteritis, transverse myelitis, ulcerative colitis, uveitis, vasculitides such as dermatitis herpetiformis vasculitis, vitiligo, and Wegener's granulomatosis.

Examples of inflammatory disorders which can be prevented, treated or managed in accordance with the methods of the invention include, but are not limited to, asthma, encephilitis, inflammatory bowel disease, chronic obstructive pulmonary disease (COPD), allergic disorders, septic shock, pulmonary fibrosis, undifferentiated spondyloarthropathy, undifferentiated arthropathy, arthritis, inflammatory osteolysis, and chronic inflammation resulting from chronic viral or bacterial infections.

Thus, the antibodies and antigen-binding fragments of the present invention have utility in the treatment of inflammatory and autoimmune diseases.

Diagnostic Uses

In some aspects, the present disclosure provides a diagnostic method for detecting the presence of a TIM-3 protein in vitro (e.g., in a biological sample, such as a tissue biopsy, e.g., from a cancerous tissue) or in vivo (e.g., in vivo imaging in a subject). The method includes: (i) contacting the sample with an antibody molecule described herein, or administering to the subject, the antibody molecule; (optionally) (ii) contacting a reference sample, e.g., a control sample (e.g., a control biological sample, such as plasma, tissue, biopsy) or a control subject with an antibody molecule described herein; and (iii) detecting formation of a complex between the antibody molecule, and the sample or subject, or the control sample or subject, wherein a change, e.g., a statistically significant change, in the formation of the complex in the sample or subject relative to the control sample or subject is indicative of the presence of TIM-3 in the sample. The antibody molecule can be directly or indirectly labeled with a detectable substance to facilitate detection of the bound or unbound antibody. Suitable detectable substances include various enzymes, prosthetic groups, fluorescent materials, luminescent materials and radioactive materials, as described above and described in more detail below.

The term “sample,” as it refers to samples used for detecting polypeptides includes, but is not limited to, cells, cell lysates, proteins or membrane extracts of cells, body fluids such as blood, or tissue samples.

Complex formation between the antibody molecule and TIM-3 can be detected by measuring or visualizing either the antibody molecule bound to the TIM-3 antigen or unbound antibody molecule. Any suitable detection assays can be used, and conventional detection assays include an enzyme-linked immunosorbent assays (ELISA), a radioimmunoassay (RIA) or tissue immunohistochemistry. Alternative to labeling the antibody molecule, the presence of TIM-3 can be assayed in a sample by a competition immunoassay utilizing standards labeled with a detectable substance and an unlabeled antibody molecule. In this assay, the biological sample, the labeled standards and the antibody molecule are combined and the amount of labeled standard bound to the unlabeled binding molecule is determined. The amount of TIM-3 in the sample is inversely proportional to the amount of labeled standard bound to the antibody molecule.

In some aspects, the present disclosure provides methods of using an anti-TIM-3 antibody molecule to diagnose sepsis, SIRS (Systemic Inflammatory Response Syndrome), preeclampsia, or glomerulonephritis. Sepsis is often accompanied by a downregulation of TIM-3 (Yang et al., J Immunol. 2013 Mar. 1; 190(5):2068-79) so lowered levels of TIM-3 are indicative of sepsis while normal levels of TIM-3 are an indication that sepsis is not present. In SIRS and preeclampsia, TIM-3 levels are downregulated in peripheral lymphocytes (Miko et al., PLoS ONE 8(8): e71811), so lowered levels of TIM-3 are indicative of SIRS or preeclampsia, while normal levels of TIM-3 are an indication that SIRS and preeclampsia are not present. In glomerulonephritis, TIM-3 can be upregulated (see Schroll et al., Am J Pathol 2010 April; 176(4):1716-1742) so elevated levels of TIM-3 are indicative of glomerulonephritis, while normal levels are an indication that glomerulonephritis is not present.

In some embodiments, the nucleic acid can comprise a nucleotide sequence encoding at least one, two, or three CDRs from a light chain variable region having an amino acid sequence as set forth in Tables 1-4, or a sequence substantially homologous thereto (e.g., a sequence at least about 85%, 90%, 95%, 99% or more identical thereto, and/or having one or more substitutions, e.g., conserved substitutions). In some embodiments, the nucleic acid can comprise a nucleotide sequence encoding at least one, two, three, four, five, or six CDRs from heavy and light chain variable regions having an amino acid sequence as set forth in Tables 1-4, or a sequence substantially homologous thereto (e.g., a sequence at least about 85%, 90%, 95%, 99% or more identical thereto, and/or having one or more substitutions, e.g., conserved substitutions).

In certain embodiments, the nucleic acid can comprise a nucleotide sequence encoding at least one, two, or three CDRs from a heavy chain variable region having the nucleotide sequence as set forth in Tables 1-4, a sequence substantially homologous thereto (e.g., a sequence at least about 85%, 90%, 95%, 99% or more identical thereto, and/or capable of hybridizing under the stringency conditions described herein). In some embodiments, the nucleic acid can comprise a nucleotide sequence encoding at least one, two, or three CDRs from a light chain variable region having the nucleotide sequence as set forth in Tables 1-4, or a sequence substantially homologous thereto (e.g., a sequence at least about 85%, 90%, 95%, 99% or more identical thereto, and/or capable of hybridizing under the stringency conditions described herein).

A polynucleotide may comprise modified nucleotides, such as methylated nucleotides and nucleotide analogs. The sequence of nucleotides may be interrupted by non-nucleotide components. A polynucleotide may be further modified after polymerization, such as by conjugation with a labeling component. The nucleic acid may be a recombinant polynucleotide, or a polynucleotide of genomic, cDNA, semisynthetic, or synthetic origin which either does not occur in nature or is linked to another polynucleotide in a nonnatural arrangement.

In some aspects, the application features host cells and vectors containing the nucleic acids described herein. The nucleic acids may be present in a single vector or separate vectors present in the same host cell or separate host cell, as described in more detail hereinbelow.

Vectors

Further provided herein are vectors comprising nucleotide sequences encoding an antibody molecule described herein. In some embodiments, the vectors comprise nucleotides encoding an antibody molecule described herein. In some embodiments, the vectors comprise the nucleotide sequences described herein. The vectors include, but are not limited to, a virus, plasmid, cosmid, lambda phage or a yeast artificial chromosome (YAC).

Numerous vector systems can be employed. For example, one class of vectors utilizes DNA elements which are derived from animal viruses such as, for example, bovine papilloma virus, polyoma virus, adenovirus, vaccinia virus, baculovirus, retroviruses (Rous Sarcoma Virus, MMTV or MOMLV) or SV40 virus. Another class of vectors utilizes RNA elements derived from RNA viruses such as Semliki Forest virus, Eastern Equine Encephalitis virus and Flaviviruses.

Additionally, cells which have stably integrated the DNA into their chromosomes may be selected by introducing one or more markers which allow for the selection of transfected host cells. The marker may provide, for example, prototropy to an auxotrophic host, biocide resistance, (e.g., antibiotics), or resistance to heavy metals such as copper, or the like. The selectable marker gene can be either directly linked to the DNA sequences to be expressed, or introduced into the same cell by cotransformation. Additional elements may also be needed for optimal synthesis of mRNA. These elements may include splice signals, as well as transcriptional promoters, enhancers, and termination signals.

Once the expression vector or DNA sequence containing the constructs has been prepared for expression, the expression vectors may be transfected or introduced into an appropriate host cell. Various techniques may be employed to achieve this, such as, for example, protoplast fusion, calcium phosphate precipitation, electroporation, retroviral transduction, viral transfection, gene gun, lipid based transfection or other conventional techniques. In the case of protoplast fusion, the cells are grown in media and screened for the appropriate activity.

Methods and conditions for culturing the resulting transfected cells and for recovering the antibody molecule produced are known to those skilled in the art, and may be varied or optimized depending upon the specific expression vector and mammalian host cell employed, based upon the present description.

The dissociation constants (K_(D)) of two such antibodies, ABTIM3 and anti-TIM-3 #2, as measured by surface plasmon resonance, is summarized in FIG. 2A. In FIGS. 2B and 2C, the binding of various anti-TIM-3 antibodies, including ABTIM3, to cells transfected with human TIM-3 was measured using flow cytometry. Next, three antibodies, ABTIM3, anti-TIM-3 #2, and anti-TIM-3 #3, and a control antibody were assayed for the ability to bind cynomolgus TIM-3 in cells transfected with cynoTIM-3. FIG. 2D shows that ABTIM3 has the strongest affinity for cynomolgus TIM-3 out of the three antibodies tested. FIG. 2E tests seven anti-human-TIM-3 antibodies for the ability to bind cynomolgus TIM-3, and shows that ABTIM3 binds with the highest affinity. Overall, the experiments indicate that ABTIM3 has strong (sub-nanomolar) affinity for both human and cynomolgus TIM-3.

The ability of three anti-TIM-3 antibodies, including ABTIM3, to bind to human TIM-4 expressed in CHO cells and murine TIM-3 expressed in cells was also measured by flow cytometry. Human TIM-3 has about 23% sequence identity with human TIM-4. Murine TIM-3 has about 66% sequence identity with human TIM-3 and 64% sequence identity with cynomolgus TIM-3. The results from these assays show that ABTIM3 does not bind to human TIM-4. ABTIM3 is also not cross-reactive with murine TIM-3. Taken together with the binding assay results described above, ABTIM3 antibody is specific for human and cynomolgus TIM-3.

In a cross-blocking experiment, ABTIM3 was shown to cross-block anti-TIM-3 #2, suggesting that these antibodies bind to epitopes that are near each other, and possibly overlap, although the two epitopes are not necessarily identical.

The ability of TIM-3 antibodies, e.g., ABTIM3, to bind to activated PBMCs expressing TIM-3 was also assessed. Whole human PBMCs from a donor were stimulated for 10 days with platebound CD3/CD28 (1 μg/ml each), in the presence of 10 ng/ml recombinant human IL-12. Cells were ficolled to remove dead cells and reactivated for three days with the same stimulus. Antibodies that bind to TIM-3, e.g., ABTIM3 and anti-TIM-3 #2, were compared, and anti-PD-1, anti-PD-L1, and anti-LAG-3 antibodies, and mouse IgG1 were used as control antibodies. Cells were incubated with the antibodies at various concentrations from 0.001 to 100 μg/ml, and the antibody binding to the cells was analyzed by flow cytometry. Cells were gated for CD4 or CD8 positive populations, and mean fluorescence intensity (MFI) for each antibody and concentration was plotted on a graph. Dissociation constant (K_(D)) values were then calculated. The results from the assays are shown in Table 7 below.

TABLE 7 K_(D) values for anti-TIM-3 binding to activated PBMCs CD4 gated PBMCs CD8 gated PBMCs Antibody K_(D) K_(D) ABTIM3 0.29 nM 0.30 nM Anti-TIM-3 #2 2.84 nM 3.14 nM Anti-PD-L1 control 0.20 nM 0.30 nM Anti-LAG-3 control 2.33 nM Anti-PD-1 control 22.8 nM 85.9 nM

These results demonstrate that ABTIM3 was able to bind to TIM-3 expressed on activated PBMCs.

Example 2. Domain Analysis of Anti-TIM-3 Antibody Binding to TIM-3

TIM-3 has an extracellular IgV domain and a mucin domain. The regions of TIM-3 bound by each of five antibodies was determined using a recombinant construct that replaced the IgV domain of TIM-3 with the IgV domain of PD-1, and this construct is depicted in FIG. 3A. FIG. 3B shows that the anti-TIM-3 monoclonal antibody (anti-TIM-3 #3), and two anti-PD-L1 control monoclonal antibodies (anti-PD-L1 #1 and #2), bind to the chimeric protein of FIG. 3A, while anti-TIM-3 #2 and ABTIM3 do not substantially bind. This result suggests that the anti-TIM-3 monoclonal antibodies anti-TIM-3 #2 and ABTIM3 bind to the IgV domain of TIM-3, while anti-TIM-3 #3 binds to the mucin domain of TIM-3. The dissociation constant (K_(D)) values were calculated for each tested antibody for the recombinant construct are shown in Table 8.

TABLE 8 K_(D) values for binding to PD-L1 IgV/TIM-3 mucin construct Antibody Antigen K_(D) Anti-PD-L1 #1 PD-L1 IgV domain 0.52 nM Anti-PD-L1 #2 PD-L1 IgV domain 0.38 nM Anti-TIM-3 #3 TIM-3 mucin domain 2.71 nM Anti-TIM-3 #2 TIM-3 No binding to the chimeric protein ABTIM3 TIM-3 No binding to the chimeric protein

Example 3. TIM-3 Binding to PtdSer is Blocked by Anti-TIM-3 Antibodies

TIM-3 binds to PtdSer (phosphatidylserine), a lipid that is typically present on the surface of apoptotic cells and not normal cells. Anti-CD95-treated WR19L(Fas) cells were cultured under conditions that promote PtdSer accumulation on the cell surface (flipping of PtdSer from the inner membrane to external exposure upon induction of apoptosis). TIM-3-Ig (huTIM-3 extracellular domain fused to an Ig Fc region) was added to the cells, and binding of TIM-3-Ig to the cells was assayed in the presence of various antibodies. As shown in FIG. 4, several anti-TIM-3 mAbs, including ABTIM3, anti-TIM-3#5, and anti-TIM-3 #2, inhibit the binding of TIM-3 to PtdSer.

Example 4. IFN-Gamma Secretion of CD4+ Cells is Enhanced by Anti-TIM-3 Antibodies

The ability of four antibodies to enhance IFN-gamma secretion and proliferation of IL-12 stimulated CD4+ cells was assayed. This assay used the observation that a high dose of IL-12 induces expression of TIM-3 and yields an exhausted phenotype in T cells (see Yang et al., J. Clin. Invest. 122:4 p 1271 2012). FIG. 5A shows four panels, each of which indicates the results of an experiment where cells were exposed to an antibody selected from ABTIM3, anti-TIM-3 #2, mIgG1, and anti-PD-L antibody (anti-PD-L1 control). After PMA/ionomycin restimulation and fixation and permeabilization of cells, the resulting IFN-gamma levels were measured by flow cytometry (y axis) and proliferation was measured by CFSE fluorescence (x axis). FIG. 5B quantifies IFN-gamma expression in cells exposed to these four antibodies. From left to right, the bars in FIG. 5B correspond to antibodies ABTIM3, anti-TIM-3 #2, anti-PD-L1 control, and mIgG1.

Example 5. TIM-3 Blockade Enhances In Vitro Functional Activity

5.1 TIM-3 Blockade Enhances In Vitro Cytotoxic Activity of Purified NK Cells

TIM-3 is highly expressed endogenously on NK (natural killer) cells; its expression is further induced on activated NK cells. TIM-3 may act to restrain NK cell function, as do other inhibitory receptors. See Ndhlovu et al., Blood 119:3734, 2012, and Silva et al., Cancer Immunol Res 2:410, 2014. Accordingly, the ability of ABTIM3 and other anti-TIM-3 antibodies to enhance NK cell cytotoxic activity was assayed.

In this assay, NK cells were purified from whole blood by negative bead selection and then incubated with antibody (10 μg/mL) at 37° C. After 1 hour, target K562 cells were added. After a 4-hour incubation at 37° C., the percent of K562 cell killing was measured. Antibody ABTIM3 resulted in elevated levels of K523 cell killing relative to anti-TIM-3 #2 or the isotype control.

5.2 TIM-3 Blockade Increases Proliferation from Autologous T-DC Co-Cultures

TIM-3 can be expressed on dendritic cells (DCs) and T cells. Naïve T cells and dendritic cells were isolated from donor samples. Naïve T cells and conventional DCs were cocultured for four days in the presence of anti-CD3/CD28. ABTIM3 was added at varying doses, 0.01 μg/mL, 0.1 μg/mL, 1 μg/mL, 5 μg/mL, and 25 μg/mL, to the co-culture. Cell proliferation was detected by a CFSE proliferation assay, which relies on dilution of CFSE staining to detect proliferating cells.

As shown in FIG. 22, the presence of ABTIM3 at every tested dosage resulted in an increase in proliferating cells, as represented by CFSE-diluted cells, compared to no antibody and the mouse isotype (IgG1) control.

Example 6. Characterization of Humanized Anti-TIM-3 Antibody

6.1 Generation of Humanized Anti-TIM-3 Antibodies

The murine anti-TIM-3 antibody ABTIM3 was humanized by grafting the CDRs, e.g., provided in Table 3, to human IgG4 constant region, with a stabilized hinge region containing the S228P mutation. Additional modifications were made to the CDR2 of the heavy chain by mutating the putative deamidation site from N at position 6 of HCDR (Kabat), or position 4 of the HCDR2 (Chothia) to S or Q to remove the deamidation site. Other modifications included using alternative frameworks. The unique heavy chains and light chains combined in various combinations to generate a small library of unique humanized mAbs.

6.2 Binding Assays

The binding capability of the humanized mAbs generated were tested by competition binding with the parent murine anti-TIM-3 antibody in a fluorescence-activated sorting assay. A representative graph depicting the results from the FACs-based competition assay comparing the binding between the parent murine anti-TIM-3 antibody and 4 humanized anti-TIM-3 antibodies (ABTIM3-hum01, ABTIM3-hum04, ABTIM3-hum07, and ABTIM3-hum08), and hIgG4 control is shown in FIG. 7.

The results from multiple surface plasmon resonance Biacore binding assays for a panel of humanized anti-TIM-3 antibodies are summarized in Table 9.

TABLE 9 Biacore K_(D) values for a panel of anti-TIM-3 antibodies KD (nM) KD (nM) KD (nM) KD (nM) Apr. 7, Apr. 29, May 1, May 30, Clone 2014 2014 2014 2014 ABTIM3-hum02 0.308 0.269 0.174 ABTIM3-hum03 0.351 0.16 0.314 ABTIM3-hum05 0.313 0.279 0.332 ABTIM3-hum06 0.498 0.214 0.364 ABTIM3-hum09 0.161 ABTIM3-hum10 0.107 ABTIM3-hum11 0.194 ABTIM3-hum12 0.355 ABTIM-hum01 0.23 ABTIM-hum04 0.172 ABTIM3-hum01 0.103 0.114 0.193 ABTIM3-hum07 0.135 0.199 0.196 ABTIM3-hum08 0.123 0.309 0.175 ABTIM3-hum04 0.216 All of the tested humanized mAbs were demonstrated to have relatively the same affinity as each other and the parent murine anti-TIM-3 antibody, within 0.1-0.5 nM K_(D).

6.3 Binding to TIM-3 Expressing Cells

The humanized anti-TIM-3 antibodies were assayed for binding to TIM-3 expressing cells using fluorescence activated cell sorting and Biacore assays, described in Example 1. In FIG. 8A, the binding of various humanized anti-TIM-3 antibodies to cells transfected with human TIM-3 was measured using flow cytometry. ABTIM3 was used as a positive control. Negative controls include hIgG4, goat anti-human, and goat anti-mouse secondary Ab-FITC. The results from the flow cytometry competition assay were used to determine the dissociation constant (K_(D)) for cells expressing human TIM-3, as shown in Table 10 below.

TABLE 10 K_(D) values for binding to cells expressing huTIM-3. Antibody K_(D) (nM) ABTIM3-hum03 0.887 ABTIM3-hum11 0.906 ABTIM3-hum21 0.917 ABTIM3 1.04

A competition binding assay was also performed to assess binding of the humanized anti-TIM-3 antibodies, ABTIM3-hum03 and ABTIM3-hum11, to cells expressing human TIM-3, while in the presence of the parental murine antibody, ABTIM3. As shown in FIG. 8B, the humanized anti-TIM-3 antibodies competed with ABTIM3.

The K_(D) values for two humanized anti-TIM-3 antibodies for recombinant TIM-3-Ig fusion proteins were assayed by surface plasmon resonance in a Biacore assay, as shown in Table 11.

TABLE 11 Biacore K_(D) values for TIM-3-Ig cynoTIM- huTIM- mTIM- ratTIM- 3/Fc 3/his 3/his 3/Fc ABTIM3- KD(M) 1.04E−09 1.24E−10 hum03 KD(M) 3.89E−09 1.84E−10 5.10E−08 KD(M) 3.08E−09 7.58E−11 Mean 2.67E−09 1.28E−10 KD(M) ABTIM3- KD(M) 1.24E−09 1.55E−10 hum11 KD(M) 3.14E−09 2.26E−10 KD(M) 5.04E−09 1.09E−10 2.97E−07 Mean 3.14E−09 1.63E−10 KD(M)

These results show that the humanized TIM-3 antibodies have similar binding affinity with human and cynomolgus proteins. The humanized TIM-3 antibodies showed very weak binding affinity to rat TIM-3/Fc protein, in the order of 1/1000 compared to the binding affinity with huTIM-3/Fc.

Example 7: X-Ray Crystal Structure of the Human TIM-3/ABTIM3-Hum21 Fab Complex

The crystal structure of a human TIM-3 (IgV domain, SEQ ID NO: 220, Table 12) bound to the Fab fragment of a humanized anti-TIM-3 antibody ABTIM3-hum21 (SEQ ID NO: 221 and 222, Table 12) was determined. As detailed below, TIM-3 was co-expressed with MGB220 Fab in mammalian cells to produce purified complex. Protein crystallography was then employed to generate atomic resolution data for TIM-3 bound to ABTIM3-hum21 Fab to define the epitope. ABTIM3-hum21, a humanized antibody from a parental murine antibody, comprises an IgG1 framework and the variable heavy chain of SEQ ID NO: 84, and the variable light chain of SEQ ID NO: 88. ABTIM3-hum21 differs by only one amino acid in heavy chain CDR2 from other humanized anti-TIM antibodies described herein and this different amino acid (Gln55) is far away (>6 Å) from the epitope and thus would not change antigen binding, which indicates that the crystal structure results obtained are applicable to the other humanized antibodies described herein.

7.1 Protein Production

The sequences of TIM-3 and ABTIM3-hum21 Fab produced for crystallography are shown in Table 12. The construct of TIM-3 comprises residues 22 to 130 (underlined) of human TIM-3 (UniProt identifier Q8TDQ0, SEQ ID NO: 129), along with N- and C-terminal residues from recombinant expression vector (shown in lower case letters, SEQ ID NO: 130). The N-terminal signal sequence from mouse IgG kappa light chain was used for secreted expression of TIM-3 and was cleaved during expression, leaving intact N-terminus of TIM-3. The C-terminus of TIM-3 was fused with a 6×His tag (SEQ ID NO: 133) for purification. For ABTIM3-hum21 Fab, the sequences of heavy (SEQ ID NO: 131) and light (SEQ ID NO: 132) chains are shown.

TIM-3 was co-expressed with ABTIM3-hum21 Fab in Expi293® cells to produce complex for crystallography. In detail, 0.3 mg of plasmid encoding TIM-3 was mixed with 0.15 mg of plasmid encoding the heavy chain of ABTIM3-hum21 Fab and 0.15 mg of plasmid encoding the light chain of ABTIM3-hum21 Fab, diluted into 30 mls of Opti-MEM® I medium (Life Technologies), and incubated with 1.5 mgs of Polyethylenimine (Polysciences) in 30 mls of the same medium for 30 min. The mixture was then added into 0.6 L of Expi293® cells growing in suspension in Expi293® Expression medium (Life Technologies) at 2 million cells/ml at 37° C. with 8% of CO2 for transfection. After 5 days, the medium containing TIM-3/ABTIM3-HUM21 Fab complex was harvested by centrifugation. Five mls of Ni-NTA resin was added into the medium and kept stirring at 4° C. overnight. The next day the beads were packed into a gravity column and washed with 25 mM Hepes pH 7.4, 150 mM NaCl (HBS) supplemented with 20 mM of imidazole. The complex was eluted with 3 column volumes (CV) of HBS with 500 mM of imidazole, and then dialyzed in HBS at 4° C. overnight. The next day, the complex was incubated with 1/10 (w/w) of PNGaseF (purified in-house) at 37° C. overnight to remove N-linked glycosylation. After deglycosylation, the mixture was bound back to 5 mls of Ni-NTA resin, washed with HBS to remove PNGaseF and eluted with HBS plus 500 mM of imidazole. The eluate was then concentrated and loaded onto HiLoad 16/600 Superdex 75 PG (GE Healthcare) size exclusion column equilibrated in HBS. Peak fractions containing purified TIM-3/ABTIM3-hum21 Fab complex were analyzed by SDS-PAGE, pooled and concentrated for crystallization.

7.2 Crystallization and Structure Determination

TIM-3/ABTIM3-hum21 Fab complex was concentrated to 12.5 mg/ml, centrifuged at 20,000 g for 10 min, and screened for crystallization. Crystals for data collection were grown by hanging drop vapor diffusion at 20° C. In detail, 0.1 μl of the TIM-3/ABTIM3-hum21 Fab complex was mixed with 0.1 μl of reservoir solution containing 0.04 M potassium phosphate monobasic, 16% (w/v) PEG 8000 and 20% (v/v) Glycerol. The drop was then equilibrated against 45 μl of the same reservoir solution. Before data collection, the crystals were flash cooled in liquid nitrogen.

Diffraction data were collected at beamline 17-ID at the Advanced Photon Source (Argonne National Laboratory, USA), and processed using Autoproc (version 1.1.5, Global Phasing, LTD). The data of TIM-3/ABTIM3-hum21 Fab was processed to 2.0 Å in space group P2₁ with cell dimensions a=84.3 Å, b=93.0 Å, c=85.3 Å, alpha=90°, beta=114°, and gamma=90°. The structure of the complex was solved by molecular replacement using Phaser (version 2.5.5, McCoy et al., (2007) J. Appl. Cryst. 40:658-674) with structures of mouse TIM-3 (PDB ID: 3KAA) and a Fab (in-house structure) as search models. The final model was built in COOT (version 0.6 pre, Emsley & Cowtan (2004) Acta Cryst. D60:2126-2132) and refined using Phenix (version 1.9, Afonine et al., (2012) Acta Cryst. D68:352-367). The R_(work) and R_(free) values were 17.5% and 22.1%, respectively; and the root-mean-square (r.m.s) deviation values of bond lengths and bond angles are 0.007 Å and 1.1°, respectively.

Epitope was defined as residues of TIM-3 that contain atoms within 5 Å to any atom in ABTIM3-hum21 Fab, identified by CONTACT in CCP4 program suite (version 6.2.0, Winn et al., (2011) Acta. Cryst. D67:235-242) and listed in Table 13. There are 2 copies of TIM-3/ABTIM3-hum21 Fab complexes in the asymmetric unit (the smallest unique unit in the crystal), only those antibody-contacting residues that are common in both copies are listed as epitope residues.

7.3 Epitope of ABTIM3-hum21 on TIM-3

The crystal structure of the TIM-3/ABTIM3-hum21 Fab complex was used to identify the epitope of ABTIM3-hum21 on TIM-3. The interaction surface on TIM-3 by ABTIM3-hum21 was formed by several continuous and discontinuous (i.e. noncontiguous) sequences: namely residues Val24, Glu25, Tyr26, Phe39, Tyr40, Thr41, Gly56, Ala57, Cys58, Pro59, Val60, Phe61, Ser105, Gly106, Ile107, Asn119, Asp120, Glu121, Lys122, Phe123, Asn124, Leu125, Lys126, Leu127, and Val128 as detailed in Table 13. These residues form the exemplary three-dimensional conformational epitope that is recognized by ABTIM3-hum21 (FIG. 9).

TABLE 13 Interactions between human TIM-3 and ABTIM3-hum21. TIM-3 residues are numbered as in UniProt entry Q8TDQ0 (SEQ ID NO: 219). The antibody residues are numbered based upon their linear amino acid sequence (SEQ ID NO: 221 and 222) and corresponding chains are labeled (“H” for heavy chain, “L” for light chain). TIM-3 residues shown here have at least one atom within 5 Å to an atom in ABTIM3-hum21, to account for potential water mediated interactions.

7.4 ABTIM3-hum21 v.s. TIM-3 Ligands

The identification of the epitope of TIM-3 recognized by the anti-TIM-3 antibody indicates that binding of some of the TIM-3 ligands may be disrupted by antibody binding. The known ligands of TIM-3 include CEACAM-1, phosphatidylserine (PtdSer), HMGB1, and Galectin-9 (Gal-9).

With respect to CEACAM-1, a recent study has showed that CEACAM-1 is a ligand for TIM-3 required for its ability to mediate T-cell inhibition, and this interaction has a crucial role in regulating autoimmunity and anti-tumour immunity (Huang et al., (2014) Nature). The same study also identified, both biochemically and structurally, the crucial amino acid residues of TIM-3 mediating its binding to CEACAM-1 (FIG. 10A). The ABTIM3-hum21 epitope on TIM-3 overlaps with these CEACAM-1-binding residues (FIG. 10A), including C58, N119 and K122. For example, K122 forms hydrogen bond N42 of CEACAM-1, but is complete blocked by ABTIM3-hum21 (FIG. 10B). Superimposition of the crystal structures obtained from the TIM-3/ABTIM3-hum21 Fab and the TIM-3/CEACAM-1 (PDB ID: 4QYC) complexes results in a significant clash between ABTIM3-hum21 and CEACAM-1 (FIG. 10C). Altogether, these data suggests that ABTIM3-hum21 disrupts CEACAM-1 binding.

With respect to PtdSer, the FG loop and CC′ loop of TIM-3 form a pocket (often referred to as the metal ion-dependent ligand binding site (MILIBS)) that has been shown by crystal structure to bind Ca²⁺ and PtdSer simultaneously (DeKruyff, et al., (2010) J Immunol. 184(4):1918-1930). This binding is thought to help TIM-3-expressing cells engage and penetrate the membrane of apoptotic cells (which displays PtdSer) for engulfment. The crystal structure of TIM-3/ABTIM3-hum21 Fab indicates that ABTIM3-hum21 binds the PtdSer-binding loops of the human TIM-3 IgV domain; and the attacking angle of the antibody suggests it will prevent PtdSer-mediated membrane penetration of TIM-3 (FIG. 11).

With respect to HMGB1, it has been reported to interact with TIM-3 to help tumor-associated dendritic cells suppress nucleic acid-mediated innate immune response (Chiba et al., (2012) Nat. Immunol. 13(9):832-842). The amino acid residue at position 62 of TIM-3 (Q in mouse, E in human TIM-3) has been shown to be important for mouse HMGB1 binding to mouse TIM-3. E62 is not present in the ABTIM3-hum21 epitope, though it is very close to the two epitope residues V60 and F61, thus there is a chance that ABTIM3-hum21 can block HMGB1 binding depending on the attacking angle of HMGB1 to TIM-3.

With respect to Gal-9, it has been shown to bind mouse TIM-3 to negatively regulate Th1-immune response (Zhu et al., (2005) Nat. Immunol. 6(12):1245-1252). However, it has also been reported that human TIM-3 on T cells does not act as a receptor for Gal-9 (Leitner et al., (2013) PLoS Pathog. 9(3):e1003253). From the crystal structure of human TIM-3/ABTIM3-hum21 Fab, half of the proposed Gal-9 binding site in mouse TIM-3 is not conserved in human TIM-3 (N74 and N90 in mouse TIM-3 become D74 and R89 in human TIM-3), i.e. this half-site in human TIM-3 will not be able to bind Gal-9. The left-over half site (N33 and N99 in human TIM-3) is conserved but is far away from the ABTIM3-hum21 epitope on TIM-3 (FIG. 9A). Therefore, even if Gal-9 is a ligand of human TIM-3, ABTIM3-hum21 will not disrupt the binding of Gal-9 to human TIM-3.

7.5 Hydrogen-Deuterium Exchange Experimental Setup

HDx/MS experiments were performed using methods similar to those described in the literature (Chalmers et al., (2006) Anal. Chem. 78(4):1005-1014). The experiments were performed on a Waters HDx/MS platform, which includes a LEAP autosampler, nanoACQUITY UPLC and Synapt G2 mass spectrometer. The deuterium buffer used to label the protein backbone of human TIM-3 (aa22-135; SEQ ID NO: 139) was 25 mM HEPES, 150 mM NaCl, 5 mM CaCl₂ pH7.4 with deterium; the overall percentage of deuterium in the solution was 94.2%. For human TIM-3 (aa22-135) deuterium labeling experiments in the absence of antibody, 300 pmol of human TIM-3 (aa22-135), volume of 7.7 μl, was diluted using 100 al of the deuterium buffer in a chilled tube and incubated for 15 minutes on a rotator at 4° C. The labeling reaction was then quenched with 100 al of chilled quench buffer at 2° C. for five minutes followed by injected onto the LC-MS system for automated pepsin digestion and peptide analysis.

For human TIM-3 (aa22-135) deuterium labeling experiments in the presence of antibodies, 400 pmol of ABTIM3-hum03 or ABTIM3-hum11 was first immobilized on Thermo Protein G Plus beads and cross-linked using disuccinimidyl suberate (DSS). To perform the labeling experiments, the antibody beads (containing 400 pmol antibody) were incubated with 300 pmol human TIM-3 (aa22-135) for 25 minutes at 4° C. After 25 minutes the beads were washed with 200 al of HEPES buffer. Then 200 al of chilled deuterium buffer (87.5% deuterium) was added and the complex was incubated for 15 minutes at 4° C. After 15 minutes, the deuterium buffer was spun out and the labeling reaction was quenched with 200 al of chilled quench buffer on ice for 4 minutes. After spinning the sample for 30 seconds in a centrifuge, the quenched solution was injected onto the LC-MS system for automated pepsin digestion and peptide analysis.

All deuterium exchange experiments were quenched using 1 M TCEP and 6 M urea (pH 2.6). After quenching, the exchanged antigen was subjected to on-line pepsin digestion using a Poroszyme Immobilized Pepsin column (2.1×30 mm) at 12° C. followed by trapping on a Waters Vanguard HSS T3 trapping column. Peptides were eluted from the trapping column and separated on a Waters BEH C18 1×100 mm column (maintained at 1° C.) at a flow rate of 40 al/min using a binary 8.4 minute gradient of 2 to 35% B (mobile phase A was 99.9% water and 0.1% formic acid; mobile phase B was 99.9% acetonitrile and 0.1% formic acid).

7.6 Hydrogen-Deuterium Exchange Results

For human TIM-3 93% of the sequence was monitored by deuterium exchange as shown in FIG. 18. In this figure each bar represents a peptide that is monitored in all deuterium exchange experiments. For differential experiments between antibody bound and unbound states it is informative to examine the difference in deuterium uptake between the two states. In FIG. 19 a negative value indicates that the TIM-3-antibody complex undergoes less deuterium uptake relative to TIM-3 alone. A decrease in deuterium uptake can be due to protection of the region from exchangeable deuterium or stabilization of the hydrogen bonding network. In contrast, a positive value indicates that the complex undergoes more deuterium uptake relative to TIM-3 alone. An increase in deuterium uptake can be due to destabilization of hydrogen bonding networks (i.e. localized unfolding of the protein).

ABTIM3-hum03 shares identical CDRs with ABTIM3-hum11 except that ABTIM3-hum03 has a glutamine at position 55 in HCDR2 while ABTIM3-hum11 has an asparagine at position 55 in HCDR2. ABTIM3-hum03 shares the same CDR regions with ABTIM3-hum21. One expects these antibodies to have the same epitope on TIM-3. From FIG. 19 one observes that ABTIM3-hum03 and ABTIM3-hum11 exhibit the same protection profile which is consistent with the two antibodies sharing the same epitope. Closer examination of FIG. 19 reveals that when TIM-3 is complexed with either of the two antibodies that many regions of TIM-3 undero significant protection, typically defined as proection less than or equal to −0.5 Da (Houde et al. (2010) J. Pharma. Sci. 100(6): 2071-2086). The observation of broad protection suggests that binding of either of the two antibodies to the TIM-3 antigen cause a broad based stabilization of hydrogen bonding networks in TIM-3. This broad protection is in addition to the protection that results from solvent sheilding of the epitope at the antibody-antigen interface. Given the significant amount of broad protection, it is useful to rank order the most protected regions of TIM-3 upon antibody binding to delineat the regions likely to be involved in the epitope. TIM-3 regions that are the most protected upon ABTIM3-hum03 or ABTIM3-hum11 binding include the regions 23-25 (EVE), 41-61 (TPAAPGNLVPVCWGKGACPVF, SEQ ID NO: 140), 73-77 (RDVNY, SEQ ID NO: 141), and 121-127 (EKFNLKL, SEQ ID NO: 142). Comparing these protected regions to the X-ray crstyal structure data summarized in Table 13 shows consistent agreement indicating that the epitope determined by X-ray crystal structure is present in solution.

Example 8: TIM-3 Expression in Cancer

TIM-3 is expressed in various cancers. In this example, several different analysis methods were used to identify cancers with TIM-3 expression in which therapeutic benefit could be achieved by an anti-TIM-3 antibody.

8.1 Immunohistochemical Staining of Tumors

ABTIM-3 was used to stain various tumor tissues. TIM-3 tumor expression was identified in esophageal squamous cell carcinoma, primary and metastatic renal cell carcinoma, colorectal cancer, and leukemic stem cells in AML.

8.2 Expression Analysis in TCGA and ICGC Databases

Overall TIM-3 expression was compared in the The Cancer Genome Atlas (TCGA) database and the International Cancer Genome Consortium (ICGC) database. The following cancers were identified as among the highest expressors of TIM-3: diffuse large B cell lymphoma (DLBCL), kidney renal clear cell carcinoma (KIRC), glioblastoma multiforme (GBM), nasopharyngeal carcinoma (NPC), lung adenocarcinoma (LUAD), kidney renal papillary cell carcinoma (KIRP), mesothelioma (MESO), acute myeloid leukemia (AML), and in breast cancer, triple negative (TN) immunomodulatory (IM) subtype (FIG. 12).

Next, cancers were identified that were characterized by high TIM-3 expression in conjunction with high expression of other immune cell markers. The other immune cell markers include: T cell marker CD3e, T regulatory cell marker FoxP3, natural killer cell marker NKp30, macrophage marker CD68, and dendritic cell marker CD11c. As shown in FIG. 12, cancer indications with high expression of TIM-3 and the other immune cell marker were identified. “High” expression was quantified by 3^(rd) quartile (or top 25%) expressors across more than 34,000 cases. For TIM-3 and CD3e, the top indications were diffuse large B cell lymphoma (DLBCL), nasopharyngeal carcinoma (NPC), and kidney renal clear cell carcinoma (KIRC). For TIM-3 and FoxP3, the top indications were diffuse large B cell lymphoma (DLBCL), nasopharyngeal carcinoma (NPC), and lung adenocarcinoma (LUAD). For TIM-3 and NKp30, the top indications were diffuse large B cell lymphoma (DLBCL), nasopharyngeal carcinoma (NPC), and acute myeloid leukemia (AML). For TIM-3 and CD68, the top indications were diffuse large B cell lymphoma (DLBCL), kidney renal clear cell carcinoma (KIRC), and kidney renal papillary cell carcinoma (KIRP). For TIM-3 and CD11c, the top indications were diffuse large B cell lymphoma (DLBCL), mesothelioma (MESO) (though only a small sample was assessed), and kidney renal papillary cell carcinoma (KIRP).

A comparison was also performed of the correlation between TIM-3 or PD-1 to T cell associated or macrophage associated markers in the TCGA database. The analysis revealed correlation between TIM-3 expression and both T cell associated markers (e.g., ZAP70, CD3D, CD3G, CD8B, GZMH, GZMK, and ITK) and macrophage associated markers (e.g., LILRB4, MRC1, MSR1, SIGLEC1, TREM2, CD163, ITGAX, and ITGAM), however, TIM-3 expression is more associated with macrophage markers, especially inhibitory receptors on macrophages (e.g., LILRB4). Expression of a macrophage signature, e.g., macrophage associated markers (e.g., LILRB4, MRC1, MSR1, SIGLEC1, TREM2, CD163, ITGAX, and ITGAM) was determined for various cancers and were organized for the highest expressors of the macrophage signature in FIG. 13. The cancer indications with high expression of the macrophage signature are also the same indications with high expression of TIM-3.

Example 9: Patient Selection Based on PDL1/CD8/IFN-γ Status

For each of several types of cancer, samples from multiple patients were tested for PDL1/CD8/IFN-γ status. Each sample was classified as: triple-negative for PDL1/CD8/IFN-γ, single or double positive for these markers, or triple-positive for these markers. FIG. 14 shows that in this experiment, within a population of patients, the following types of cancer are frequently triple-positive for PDL1/CD8/IFN-γ: Lung cancer (squamous), lung cancer (adenocarcinoma), head and neck cancer, cervical cancer (squamous), stomach cancer, thyroid cancer, melanoma, and nasopharyngeal cancer. Patients having these types of cancer are good candidates for therapy with anti PD-1 antibodies and combination therapies as described herein. The likelihood of successful treatment can be further boosted by determining which patients are triple-positive for PDL1/CD8/IFN-γ, and treating the triple-positive patients with anti-TIM-3 antibodies, alone or in combination with one or more immodulators (e.g., a PD-1 inhibitor or a PD-L1 inhibitor), and/or combination therapies, as described herein.

FIG. 15 shows that within a population of patients, the following types of cancer are rarely triple positive for PDL1/CD8/IFN-γ: ER+ breast cancer and pancreatic cancer. Notably, even in cancers that are generally not positive for PDL1/CD8/IFN-γ, one can increase the likelihood of successful treatment by determining which patients are triple-positive for PDL1/CD8/IFN-γ, and treating the triple-positive patients with anti-TIM-3 antibodies, alone or in combination with one or more immodulators (e.g., a PD-1 inhibitor or a PD-L1 inhibitor), and/or combination therapies, as described herein.

FIG. 16 shows the proportion of breast cancer patients that are triple positive for PDL1/CD8/IFN-γ. Considering breast cancer in general, the proportion of triple-positives is somewhat low. However, when one focuses only on IM-TN breast cancer, it can be seen that a much larger percentage of patients is triple positive for PDL1/CD8/IFN-γ. IM-TN breast cancer is particularly difficult to treat with conventional therapies. The discovery that IM-TN breast cancer is often triple-positive for PDL1/CD8/IFN-γ opens up new avenues of therapy for this cancer with anti-TIM-3 antibodies, alone or in combination with one or more immodulators (e.g., a PD-1 inhibitor or a PD-L1 inhibitor), and/or combination therapies, as described herein.

FIG. 17 shows the proportion of colon cancer patients that are triple positive for PDL1/CD8/IFN-γ. Considering colon cancer in general, the proportion of triple-positive is somewhat low. However, when one focuses only on MSI-high (high microsatellite instability) breast cancer, it can be seen that a much larger percentage of patients is triple positive for PDL1/CD8/IFN-γ. MSI levels can be assayed using, e.g., commercially available PCR-based methods.

Gastric cancer samples were tested for levels of PDL1/CD8/IFN-γ (data not shown). It was found that in MSI-high or EBV+ gastric cancers, about 49% were positive for PDL1, and a high proportion of the PDL-positive cells were triple positive for PDL1/CD8/IFN-γ. It was also found that a proportion of PDL1-positive cells and PDL1/CD8/IFN-γ positive cells were also positive for PIK3CA. This finding suggests that these cancers may be treated with an anti-TIM-3 antibody, alone or in combination with one or more immodulators (e.g., a PD-1 inhibitor or a PD-L1 inhibitor), optionally in combination with a PIK3 therapeutic.

MSI-high CRC samples were tested for a combination of markers (data not shown). It was found that in MSI-high CRC samples, a high proportion of the PDL1/CD8/IFN-γ samples are also positive for LAG-3, PD-1 (also called PDCD1), RNF43, and BRAF. This finding suggests that these cancers may be treated with an anti-TIM-3 antibody, optionally in combination with a therapeutic that targets one or more of LAG-3, PDCD1, RNF43, and BRAF.

Squamous cell lung cancers were tested for a combination of markers (data not shown). It was found that in squamous cell lung cancer samples, a high proportion of the PDL1/CD8/IFN-γ samples are also positive for LAG-3. This finding suggests that these cancers may be treated with an anti-TIM-3 antibody, optionally in combination with a therapeutic that targets LAG-3, e.g., a LAG-3 antibody.

Papillary thyroid cancers were tested for a combination of markers including the BRAF V600E mutation (data not shown). It was found that a high proportion of thyroid cancer samples that are positive for PDL1 are also positive for BRAF V600E. This finding suggests that these cancers may be treated with an anti-TIM-3 antibody, alone or in combination with one or more immodulators (e.g., a PD-1 inhibitor or a PD-L1 inhibitor), optionally in combination with a therapeutic that targets BRAF.

Example 10: Patient Selection Based on PD-L1 Status

To enable broad examination of cancer indications for PD-1/PD-L1 based therapies, we evaluated PD-L1 expression at both the protein and mRNA level in human cancers including both lung and hepatic tumors.

PD-L1 protein expression was evaluated in a set of formalin-fixed paraffin-embedded non-small cell lung (NSCLC) adenocarcinoma (ACA), NSCLC squamous cell carcinoma (SCC), and hepatocellular carcinoma (HCC) tumors by immunohistochemistry (IHC). PD-L1 expression was scored semi-quantitatively by a manual histo-score (H-score) methodology based on staining intensity and percentage of positive tumor cells. In our IHC analysis, PD-L1 positivity (PD-L1+) was defined as an H-score≥20. In parallel, PD-L1 mRNA expression data was examined from The Cancer Genome Atlas (TCGA) in these same indications (503 NSCLC ACA, 489 NSCLC SCC, and 191 HCC) and analyzed by comparing the expression in matched normal tissues from TCGA.

With RNAseq analysis, data was calculated as log 2 (RPKM+0.1) after RSEM normalization, utilizing OmicSoft RNASeq pipelines across TCGA tumor indications. The expression of PD-L1 is elevated in NSCLC ACA and SCC, relative to that in HCC. By overlaying the distributions and comparing the expression levels across all indications in TCGA, we ranked overexpression profiles for PD-L1 and found the TCGA HCC cohort to have much reduced PD-L1 mRNA levels, with a median level of −0.8 compared to 1.3 for ACA and 1.5 for SCC, which amounts to more than a 2-fold change of median level expression. With RNAseq, our analysis defines 50% of NSCLC adenocarcinoma, 54% of NSCLC squamous cell carcinoma, and 6% of HCC as high expressers for PD-L1.

Tumor cell PD-L1 protein expression was measured in 45 lung adenocarcinoma (ACA) samples, 47 lung squamous cell carcinoma (SCC) samples, and 36 hepatocellular carcinoma (HCC) samples. 16/45 (35.6%) lung ACA, 21/47 (44.7%) lung SCC were PD-L1 positive. In contrast, PD-L1 positivity was seen in only 2/36 (5.6%) HCC samples.

In summary, with IHC and RNAseq analysis in large and independent human NSCLC and HCC sample sets, we have found PD-L1 expression to be more enriched in NSCLC than in HCC. Within NSCLC, there are comparable findings between adenocarcinoma and squamous cell carcinomas. Importantly, amongst the large number of samples (128 for IHC and 1183 for RNAseq) in the 3 indications, very good concordance is observed between protein- and mRNA-based analyses. Our finding thus establishes the basis for large scale mRNA-based data mining in TCGA for indications and patient segments that may be enriched for responses to PD-1/PD-L- and/or TIM-3 based immune therapies.

Example 11: Competition Assays Indicate Humanized Anti-TIM3 Antibodies Bind to a Similar Epitope

As described above, the epitope of TIM-3 recognized by ABTIM3-hum21 was determined by x-ray crystallography studies. ABTIM3-hum21 differs by only one amino acid in the heavy chain CDR2 from the other humanized anti-TIM3 antibodies described herein, and this different amino acid (Gln55) is far away (>6 Å) from the epitope and thus would not be expected to change antigen binding. Two different competition assays were performed to compare epitope binding between ABTIM3-hum21 and two other humanized anti-TIM3 antibodies, ABTIM3-hum03 and ABTIM3-hum11. The results of both competition assays show that both ABTIM3-hum04 and ABTIM3-hum11 effectively compete with ABTIM3-hum03 for binding to TIM3, thus demonstrating that ABTIM3-hum03 and ABTIM3-hum11 also bind to a similar epitope as ABTIM3-hum21, e.g., the epitope as described herein.

11.1 Flow Cytometry Competition Assay

K_(D) of ABTMI3-hum21 was determined by labeling ABTIM3-hum21 with phycoerythrin, incubated with 300.19 hTIM-3 expressing cells, and a binding curve was established to determine a K_(D) of 2.15.

Titrated concentrations of unlabelled hIgG1 (isotype control), ABTIM3-hum21 (positive control), ABTIM3-hum11 or ABTIM3-hum03 were mixed with ABTIM3-hum21 at its K_(D) and incubated with 300.19 hTIM-3 expressing cells at 4° C. for 3 hours. Cells were washed twice and run on an LSRFortessa flow cytometer. Data was analyzed in FlowJo and MFI (PE) values were plotted and graphed in GraphPad (Prism) software. The experiment was performed twice.

The results of the competition assay demonstrate that ABTIM3-hum11 and ABTIM3-hum03 (but not isotype control) both competed with ABTIM3-hum21 for binding with human TIM3 expressed on the 300.19 cells (FIG. 20). K_(D) for ABTIM3-hum11 and ABTIM3-hum03 was calculated from the binding curves; the calculated K_(D) for ABTIM3-hum11 was 2.276 nM and the calculated K_(D) for ABTIM3-hum03 was 2.413 nM. These results demonstrate that ABTIM3-hum11 and ABTIM3-hum03 bind to a similar or the same epitope as ABTIM3-hum21.

11.2 Biacore Competition Assay

hTIM-3/his antigen was captured by immobilized anti-His antibody (RU10000) on a CM5 chip. The first antibody was injected to reach saturation (>90%). Then the second antibody was injected to assess whether a second binding event occurs. Occurrence of a second binding event indicates that the two tested antibodies have different epitopes. Lack of a second binding event, indicates that the two antibodies may recognize and bind to the same epitope. Control assays were run where a test antibody was run with human IgG isotype control, or where the test antibody was run as the first and second antibody (e.g., self-self cycle) to observe the baseline of a binding event. Table 14 summarizes the Biacore cycles run and indicates which antibodies were used as the first and second antibody in each cycle.

TABLE 14 Summary of Biacore competition assay cycles Cycles 1^(st) Antibody 2^(nd) Antibody 1 huIgG1 huIgG1 2 huIgG1 ABTIM3-hum21 3 huIgG1 ABTIM3-hum03 4 huIgG1 ABTIM3-hum11 5 ABTIM3-hum21 huIgG1 6 ABTIM3-hum21 ABTIM3-hum21 7 ABTIM3-hum21 ABTIM3-hum03 8 ABTIM3-hum21 ABTIM3-hum11 9 ABTIM3-hum03 huIgG1 10 ABTIM3-hum03 ABTIM3-hum21 11 ABTIM3-hum03 ABTIM3-hum03 12 ABTIM3-hum03 ABTIM3-hum11 13 ABTIM3-hum11 huIgG1 14 ABTIM3-hum11 ABTIM3-hum21 15 ABTIM3-hum11 ABTIM3-hum03 16 ABTIM3-hum11 ABTIM3-hum11

Detection of the baseline and first and second binding events are recorded as RU (resonance units) and can be presented in a sensogram. A typical sensogram is shown in FIG. 21, where a binding event is shown after the 1^(st) antibody injection. After a wash, the second antibody is injected and a second binding may be detected. Significant changes in RU indicate a binding event. A summary of the changes in RU detected from the 1^(st) and 2^(nd) antibody injections from the Biacore competition assay is shown in Table 15.

TABLE 15 Summary of results from Biacore competition assay 2^(nd) Antibody Injection 1^(st) Antibody ABTIM3- ABTIM3- ABTIM3- Injection huIgG1 hum21 hum03 hum11 huIgG1 0.27 3.6 88.2 86.3 83.2 ABTIM3-hum21 95.85 4.5 6.6 7.6 8.1 ABTIM3-hum03 93.33 4.5 6.9 7.3 8.5 ABTIM3-hum11 93.48 3.8 NA¹ 5.3 7.2 ¹No value was calculated from the sensogram, due to an unknown fluid problem.

The results shown above demonstrate that injection of ABTIM3-hum21, ABTIM3-hum03, and ABTIM3-hum11 during the first antibody injection results in a binding event. Injection of ABTIM3-hum21, ABTIM3-hum03, and ABTIM3-hum11 as the second antibody after injection is human IgG1 control antibody results in a second binding event. However, injection of any of the anti-TIM3 antibodies tested here as the first and second antibodies did not result in a second binding event, demonstrating that for each pair of 1^(st) and 2^(nd) antibodies tested, there was competition for binding to the same TIM3 epitope. These results indicate that ABTIM3-hum21, ABTIM3-hum03, and ABTIM3-hum11 bind to a similar or the same epitope on human TIM3.

Example 12: Pharmacokinetic Properties of ABTIM3-hum11

Various pharmacokinetic properties of ABTIM3-hum11 were assessed in mouse and rat models. ABTIM3-hum11 was injected intravenously into mice at varying doses, 1 mg/kg, 3 mg/kg, and 10 mg/kg. Blood samples were obtained at various timepoints between 0 and 672 hours (0-28 days). 10 mg/kg ABTIM3-hum11 was injected intravenously into rats, and blood samples were obtained at various time points from 0-400 hours (0-16 days). The concentration of ABTIM3-hum11 present in the serum was determined (FIGS. 23A and 23B). The results showed that ABTIM3-hum11 is stable in both mouse and rat serum. Table 16 shows additional pharmacokinetic properties determined, including halflife (T½), peak serum concentration (Cmax), AUC up to the last measurable concentration (AUClast), and AUC as extrapolated to infinity (AUCinf).

In a toxicity study, three naïve mice were administered a single dose by intravenous injection at 1 mg/kg, 3 mg/kg, or 10 mg/kg of ABTIM3-hum11. After 28 days, no adverse events were observed, indicating that ABTIM3 antibody is tolerable in mouse models.
